general description the max4832/max4833 family of low-dropout (ldo) linear regulators feature an accurate current-limiting switch with an integrated flag or reset function. these devices operate from 2.5v to 5.5v and deliver up to 100ma of load current at a preset output voltage. preset output voltage levels are 1.8v/2.5v/2.8v/3.0v/3.3v. the max4832/max4833 offer a programmable soft- start control function to eliminate false reset during startup. the max4832 provides a flag function to noti- fy the system when the load current exceeds the limit. the max4833 provides a reset function to notify the system when the output drops below the threshold. additionally, reverse-current protection prevents cur- rent flowing from the output to the input. other features include a low 90? quiescent current, a 0.1? shut- down current. the max4832/max4833 are available in space-saving 6-pin sot23 and tdfn packages. each device is speci- fied over the -40? to +85? extended temperature range. contact factory for other programmed output volt- age versions from 1.5v to 3.3v in 100mv increments. for pin-compatible 250ma versions of this device, refer to the max4834/max4835. for pin-compatible 500ma versions of this device, refer to the max4836/max4837. applications sdio ports and devices notebook computers usb ports and devices cell phones pdas and palmtop devices gps systems features ? guaranteed minimum 100ma load current ? accurate current limit ? preset output voltages: 1.8v/2.5v/2.8v/3.0v/3.3v ? 2.5v to 5.5v supply voltage range ? adjustable soft-start ? low dropout voltage ? thermal shutdown ? reverse-current protection ? shutdown output discharge (max4833) ? low 90a supply current ? ultra-low 0.1a shutdown current ? flag and latch off (max4832) or reset (max4833) ? tiny sot23 and tdfn packages max4832/max4833 100ma ldo linear regulators with current-limiting switch ________________________________________________________________ maxim integrated products 1 ordering information 19-3372; rev 0; 7/04 for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. note: ?y?are placeholders for the output voltage levels of the devices. insert the values found in table 1 at the end of this doc- ument in the place of ?y? the ??is a placeholder for either the reset or the flag feature. insert ??in the place of ??for reset and ??for flag . ?d?is a placeholder for the reset timeout period. insert the values found in table 2 in the place of ?d.?for example, max4833eut18bd2 has a 1.8v output volt- age, reset feature, and a 30ms reset timeout period. note that ?d?applies only to the devices with reset option and does not apply to the devices with flag option. for devices with the flag option, leave dd blank. standard versions require a mini- mum order increment of 2.5k units. nonstandard versions must be ordered in 10k unit increments. contact factory for availability. * future product?ontact factory for availability. part temp range pin-package max4832 eutxy_-t* -40? to +85? 6 sot23-6 max4832ettxy_-t -40? to +85? 6 tdfn-6 max4833 eutxy_dd-t* -40? to +85? 6 sot23-6 max4833ettxy_dd-t -40? to +85? 6 tdfn-6 6 out 5 ss 4 reset (flag) 1 2 gnd 3 shdn max4832/max4833 in tdfn exposed paddle top view ( ) max4832ettxyc only. pin configurations pin configurations continued at end of data sheet. tables 1 and 2 and selector guide appear at end of data sheet.

detailed description the max4832/max4833 are ultra-low quiescent current, low-dropout linear regulators with an integrated current limiter. these devices guarantee up to 100ma drive capabilities and regulate the preset output voltage. the max4832 has a flag output that asserts low when the load current exceeds the current limit for more than the blanking time (t blank ). the max4833 has a reset output that asserts low when the regulator output volt- age is below the reset threshold voltage (v reset ). v reset is 87.5% of the nominal output voltage. figure 1 shows the simplified functional diagram and figure 2 shows the typical application circuits. flag output (max4832) the open-drain flag output goes low and the ldo? pass transistor is latched off when the current in the pass transistor is at its output current limit for more than the blanking time (t blank ). cycling in, or shdn (high to low to high) brings the device out of its latched-off state and back into normal operation. reset output (max4833) the reset output asserts when one of the following conditions occurs: the input voltage (v in ) is below the input undervolt- age lockout threshold (v uvlo ). the output voltage (v out ) is below the reset thresh- old (v reset ). shdn is pulled low. the device is in thermal shutdown. when v out > v in. reset remains low for the reset timeout period (t reset ) after reset conditions are terminated. there are four reset timeout periods available as shown in the electrical characteristics table. reset is available in a push-pull configuration as shown in the selector guide . shutdown pull shdn low to shut down the ldo and reduce the quiescent current consumption of the device from 90? to 0.1?. in shutdown mode, the pass transistor, con- trol circuit, and reference circuit are turned off. connect shdn to a supply voltage greater than v ih to turn on the ldo. max4832/max4833 100ma ldo linear regulators with current-limiting switch _______________________________________________________________________________________ 7 pin description pin sot23 tdfn name function 11 in regulator power input. bypass in to gnd with a 0.1? ceramic capacitor. install the bypass capacitor as close to the device as possible. 2 2 gnd ground 33 shdn active-low shutdown input. drive shdn low to shutdown the regulator. drive shdn high or connect to in for normal operation. flag (max4832) overcurrent flag. open-drain flag goes low when the device senses sustained current exceeding the current-limit threshold for a duration longer than the blanking time. flag is high when shdn is low or the device is in thermal shutdown. 44 reset (max4833) active-low reset output. push-pull reset goes low when the voltage at out is below the reset threshold or when the voltage at out is greater than in. reset is low when shdn is low or the device is in thermal shutdown. after the reset condition terminates, reset remains low for the duration of the reset timeout period. 55 ss soft-start control. connect a capacitor, c ss , from ss to gnd to program the output rise time at startup. no capacitor from ss to gnd gives 1ms output rise time at startup. see the soft-start response time plots in the typical operating characteristics . 6 6 out regulator output. bypass out to gnd with a 3.3? or larger ceramic capacitor. the capacitor? esr should be less than 0.2 ? for stable operation. ?p ep exposed pad. ep is internally connected to gnd. externally connect ep to gnd to provide a low thermal resistance path from the ic junction to the pc board.

shutdown discharge (max4833) out discharges through a 900 ? internal resistor during shutdown mode. reverse out to in current when the output voltage is greater than the input volt- age, the internal pass transistor turns off. to avoid reverse-charging the input source, the current at in is guaranteed to be below 3? when v out v in . current limit the max4832/max4833 include an accurate internal current-limiting circuit. out can be shorted to ground indefinitely without damaging the part. the max4832 latches off if the load current exceeds the current limit for more than the blanking time (see the flag output section). during soft-start, the device does not latch off to an overload condition. during an overload condition, the max4833 holds the current at current limit until the thermal limit is reached. once the junction tem- perature reaches +165?, thermal shutdown occurs. thermal shutdown when the junction temperature (t j ) exceeds +165?, the ldo? pass transistor turns off allowing the junction to cool. the ldo? pass transistor turns on again after the ic? junction temperature cools by 15?, resulting in a pulsed output during continuous thermal-overload conditions. soft-start during power-up, the soft-start ensures that the output ramps up slowly reducing inrush current peaks. see the soft-start response time plots in the typical operating characteristics . the soft-start time (t ss ) is given by the following equation: t ss = c ss (ms) where c ss is in nf. a soft-start capacitor (c ss ) of 10nf gives a 10ms t ss . a 1ms minimum soft-start time is fixed internally to ensure that the output rises slowly even without any external capacitor at ss pin to ground. the device is in soft-start mode when either the voltage at in or shdn is cycled high to low to high. applications information capacitor selection and regulator stability for stable operation over the full temperature range and with load currents up to 100ma, use a 3.3? (min) ceramic output capacitor with an esr <0.2 ? . to reduce noise and improve load transient response, stability, and power-supply rejection, use larger output capacitor values such as 10? (note that some ceramic capacitors exhibit large capacitance and esr variation with temper- ature). x7r capacitors provide good performance over the -40? to +85? operating temperature range. to improve power-supply rejection and transient response, use a 0.1? capacitor between in and gnd. the max4832/max4833 remain stable with purely resistive loads or current loads up to 100ma. 15kv operational esd protection a 3.3? or higher value ceramic capacitor from out to gnd provides a 15kv (human body model) protection at out. the esr value of the capacitor should be less than 0.2 ? . reset transient immunity the reset circuit is relatively immune to short duration, falling v out transients. the typical operating characteristics show a graph of the maximum transient duration vs. reset threshold overdrive for which reset is not asserted. the graph was produced using falling v out transients starting at v out and ending below the reset threshold by the magnitude indicated (reset threshold overdrive). the graph shows the maximum pulse width that a falling v out transient can typically have without triggering the reset pulse. as the amplitude of the tran- sient increases (i.e., goes further below the reset thresh- old), the maximum allowable pulse width decreases. typically, a v out transient that goes only 10mv below the reset threshold and lasts up to 54? does not trigger a reset pulse. layout when using the tdfn package, connect its exposed paddle to gnd to provide a low thermal resistance path for heat transfer from the ic junction to the printed circuit board. max4832/max4833 100ma ldo linear regulators with current-limiting switch _______________________________________________________________________________________ 9
