1/30 1a, 0.5v low input voltage, high speed ldo regulator adjustable current limit with an external component XC6604 series general description the XC6604 series is a low voltage input (0.5v) operation and provides high accuracy 15mv / 20mv and can supply large current efficiently due to its ultra low on-resistance even at low output voltages. the series is ideally suited to the applic ations which require high current in low in put/output voltages and consists of a n-ch driver transistor, a voltage reference, an error amplifier, a current limiter, a fold-back circuit, a thermal shutdown (tsd) ci rcuit, an under voltage lock out (uvlo) circuit, a soft-start circuit and a phase compensation circuit. output voltage is selectable in 0.1v increments within a range of 0.5v to 1.8v using laser trimming technology and ceramic capacitors can be used for the output stabilization capacitor (c l ). when the output current reac hes the current limit, the output voltage drops as well as the output curre nt is decreased as a function of the fo ldback circuit. the current limit can be adjustable with connecting a resistor to the i lim pin. the ce function enables the output to be tu rned off and the series to be put in stand- by mode resulting in greatly reduced power consumption. at the time of entering the stand-by mode, the series enab les the electric charge at the output capacitor (c l ) to be discharged via the internal switch. as a result the v out pin quickly returns to the v ss level. the ce pull-down function keeps the ic to be in stand-by mode even if the ce pin is left open. features maximum output current : 1a (1.3a limit) on resistance : 0.15 ? v bias =3.6v, v out =1.2v bias voltage range : 2.5v 6.0v input voltage range : 0.5v 3.0v output voltage range : 0.5v 1.8v (0.1v increments) output voltage accuracy : 0.015v v out 1.2v 0.020v v out R 1.2v ripple rejection : 60db f=1khz (v bias_psrr ) 75db f=1khz (v in_psrr ) low power consumption : 100 a (v bias ), 6.5 a (v in ) v out =1.2v stand-by current : 0.01 a (v bias ), 0.01 a (v in ) under-voltage lockout : 1.8v (v bias ), 0.4v (v in ) thermal shutdown : 150 detect, 125 release protection circuit : foldback current limit, tsd, uvlo function : soft-start ce pull-down (active high) c l high speed discharge operating ambient temperature : -40 +85 output capacitor : ceramic capacitor compatible (2.2 f) packages : usp-6c, sot-26w environmentally friendly : eu rohs compliant, pb free etr03071-001a a pplications ? ? mobile phones / smart phones ? ? digital still cameras / video cameras ? ? note pcs / tablet pcs ? ? e-book readers ? ? wireless lan typical performance characteristics typical application circuit XC6604x121mr-g 0 0.2 0.4 0.6 0.8 1 1.2 1.4 0.0 0.5 1.0 1.5 output current: i out (a) output voltage: v out (v) rlim2=0k rlim2=22k rlim2=56k rlim2=120k v bias =v ce =3.6v, v in =1.5v c bias =c in =1.0f, c l =2.2f, ta=25 www.datasheet.co.kr datasheet pdf - http://www..net/

9/30 XC6604 series operational description the voltage divided by resistors r1 and r2 is compared with t he internal reference voltage by the error amplifier. the v out pin is then driven by the subsequent output signal. the output voltage at the v out pin is controlled and stabilized by a system of negative feedback. ? v bias pin is power supply pin for output voltage control ci rcuit, protection circuit and ce circuit. also, the v bias pin supplies some current as output current. v in pin is connected to a driver tran sistor and provides output current. in order to obtain high efficient output current through low on-resistance, please take enough v gs (=v bias ? v out(e) ) of the driver transistor. ? figure1: XC6604 series, type a the XC6604 series includes a combination of a fixed current limit er circuit and a foldback short- circuit protection. when the o utput current reaches the current limit, the output voltage drops and this oper ation makes the output current foldback to be decreased. the current limit can be set freely with connecting a resistor to the i lim pin. please note about the foldback ci rcuit characteristics below; output voltage may not rise when the output voltage is lower than 0v at the ic operation start. current over the foldback current limit will not flow at the ic operation start. please use type a (with soft-start time) to prevent from inru sh current, because the circuit ma y not response to a drastic curr ent change such as the inrush current. when the i lim pin is left open, driver transistor will be forced off. current limit is calculated by the following formulas. i lim = v out t / ( r lim1 + r lim2 ) 79645.7 [a] r lim1 = v out t / ( 16.3 10 -6 ) [ ? ] i lim : current limit v out(t) : nominal output voltage r lim1 : internal current limit resistance r lim2 : external current limit resistance figure 2: XC6604 series, range of adjustable current limit output voltage range adjustable current limit v out(t) i lim 0.5v 1.8v 0.5a 1.3a XC6604 series, r lim2 connecting www.datasheet.co.kr datasheet pdf - http://www..net/
10/30 XC6604 series operational description (continued) with the XC6604 (type a), the inrush current (i rush ) from v in to v out for charging c l at start-up can be reduced and makes the v in stable. as for the XC6604, the soft-start time in the type a is opt imized internally. on the other hand, the type b of the XC6604 does not have the soft-start time function. when the junction temperature of the built -in driver transistor reaches the temperat ure limit, the thermal shutdown circuit ope rates and the driver transistor will be set to off. the ic resumes its oper ation when the thermal shutdown function is released and the ic s operation is automatically restored because the junction temperature drops to the level of the thermal shutdown release temperature. when the v bias pin and v in pin voltage drops, the output driver transistor is set to off by uvlo function to prevent false output caused by unstable operation of the inter nal circuitry. when the v bias pin voltage and the v in pin voltage rises at release voltage, the uvlo function is released. the driver transistor is turned on and start to operate voltage regulation. the XC6604 internal circuitry can be shutdown via the signal to the ce pin. in shutdown mode with ce low level voltage, the v out pin will be pulled down to the v ss level via c l discharge resistance (r dchg ) placed in parallel to r1 and r2. the ce pin has pull-down circuitry so that ce input current fl ows during ic operation. if the ce pin voltage is taken from v bias pin or v ss pin then logic is fixed and the ic will operate normally. however, suppl y current may increase as a result of through current in t he ic's internal circuitry when medium voltage is input. XC6604 series can quickly disc harge the electric charge at the output capacitor (c l ) via the internal transistor located between the v out pin and the v ss pin when a low signal to the ce pin which enables a whole ic circuit put into off stat e. when the ic is di sabled, electric cha rge at the output capacitor (c l ) is quickly discharged so that it could avoids malfuncti on. discharge time of the output capacitor (c l ) is set by the c l auto-discharge resistance (r dchg ) and the output capacitor (c l ). by setting time constant of a c l auto-discharge resistance value (r dchg ) and an output capacitor value (c l ) as ( = c l x r dchg ), the output voltage after discharge via the inte rnal transistor is calculated by the following formula. please also note r dchg is depended on v bias . when v bias is larger, r dchg is smaller. v = v out(e) e-t/ or c = ln v out(e) / v v: output voltage during discharge v out(e) : initial output voltage t: discharge time : c l r dchg with the XC6604 series, a stable output volt age is achievable even if used with low esr capacitors, as a phase compensation cir cuit is built-in. the output capacitor (c l ) should be connected as close to v out pin and v ss pin to obtain stable phase compens ation. values required for the phase compensation are as the table below. for a stable power input, pleas e connect a bias capacitor (c bias ) between the v bias pin and the v ss pin. also, please connect an input capacitor (c in ) between the v in pin and the v ss pin. in order to ensure the stable phase compensati on while avoiding run-out of values, please use the capacitor (c bias , c in and c l ) which does not depend on bias or temperature too much. the table below (figure 3) shows recommended values of c bias , c in and c l . figure 3: recommended values of c bias , c in and c l (min.) output voltage range bias capacitor input capacitor output capacitor v out(t) c bias c in c l 0.5v 1.8v 1.0 f 1.0 f 2.2 f www.datasheet.co.kr datasheet pdf - http://www..net/
11/30 XC6604 series notes on use 1. for temporary, transitional voltage drop or voltage rising phenomenon, the ic is liable to malfunction should the ratings be exceeded. 2. where wiring impedance is high, operati ons may become unstable due to noise and/ or phase lag depending on output current. pl ease keep the resistance low for the v bias , v in and v ss wiring in particular. 3. please wire the c bias , c in and c l as close to the ic as possible. 4. capacitances of these capacitors (c bias , c in, c l ) are decreased by the influenc es of bias voltage and ambient temperature. care shall be taken for capacitor selection to ensure stability of phase compensation from the point of esr influence. 5. when it is used in a quite small input / output dropout voltage, output may go into unstable operation. please test it thor oughly before using it in production. 6. torex places an importance on improv ing our products and their reliability. we request that users incorporate fail-sa fe designs and post-aging protec tion treatment when using torex products in their syst ems. www.datasheet.co.kr datasheet pdf - http://www..net/
