NCP59300 http://onsemi.com 9 applications information output capacitor and stability the NCP59300 series requires an output capacitor for stable operation. the NCP59300 series is designed to operate with ceramic output capacitors. the recommended output capacitance value is 47 f or greater. such capacitors help to improve transient response and noise reduction at high frequency. input capacitor an input capacitor of 1.0 f or greater is recommended when the device is more than 4 inches away from the bulk supply capacitance, or when the supply is a battery. small, surface ? mount chip capacitors can be used for the bypassing. the capacitor should be place within 1 inch of the device for optimal performance. larger values will help to improve ripple rejection by bypassing the input of the regulator, further improving the integrity of the output voltage. minimum load current the NCP59300 regulator is specified between finite loads. a 10 ma minimum load current is necessary for proper operation. error flag some NCP59300 series members feature an error flag circuit that monitors the output voltage and signals an error condition when the voltage is 5% below the nominal output voltage. the error flag is an open ? collector output that can sink up to 5 ma typically during a v out fault condition. the flg output is overload protected when a short circuit of the pullup load resistor occurs in the application. this is guaranteed in the full range of flg output voltage max ratings (see max ratings table). enable input some NCP59300 series members also feature an enable input for on/off control of the device. it?s shutdown state draws ?zero? current from input voltage supply (only microamperes of leakage). the enable input is ttl/cmos compatible for simple logic interface, but can be connected up to v in . overcurrent and reverse output current protection the NCP59300 regulator is fully protected from damage due to output current overload conditions. when NCP59300 output is overloaded, output current limiting is provided. this limiting is linear; output current during overload conditions is constant. the device is also capable to withstand power ? on or enable start ? up with output shorted to ground for the full recommended operating conditions range. these features are advantageous for powering fpgas and other ics having current consumption higher than nominal during their startup. thermal shutdown disables the NCP59300 device when the die temperature exceeds the maximum safe operating temperature. when (v out ? v in ) voltage difference is less than 6.5 v in the application, the output structure of these regulators is able to withstand output voltage (backup battery as example) to be applied without reverse current flow. of course the additional current flowing through the internal feedback resistor divider at the NCP59300 fix voltage versions needs to be included in the backup battery discharging calculations. adjustable voltage design the ncp/ncv59302 adjustable voltage device output voltage is set by the ratio of two external resistors as shown in figure 23. the device maintains the voltage at the adj pin at 1.24 v referenced to ground. the current in r2 is then equal to 1.24 v / r2, and the current in r1 is the current in r2 plus the adj pin bias current. the adj pin bias current flows from v out through r1 into the adj pin. the output voltage can be calculated using the formula shown in figure 23. figure 23. adjustable voltage operation v out 1.24 v 1 r1 r2 i adj r1 + + vin en vout adj gnd ncp59302 r1 r2 v out v in c in c out 47 f, ceramic thermal considerations the power handling capability of the device is limited by the maximum rated junction temperature (125 c). the p d total power dissipated by the device has two components, input to output voltage differential multiplied by output current and input voltage multiplied by gnd pin current. p d v in v out i out v in i gnd (eq. 1) the gnd pin current value can be found in electrical characteristics table and in typical characteristics graphs. the junction temperature t j is t j t a p d r ja (eq. 2) where t a is ambient temperature and r ja is the junction to ambient thermal resistance of the ncp/ncv59300 device mounted on the specific pcb.
NCP59300 http://onsemi.com 10 to maximize efficiency of the application and minimize thermal power dissipation of the device it is convenient to use the input to output voltage differential as low as possible. the static typical dropout characteristics for various output voltage and output current can be found in the t ypical characteristics graphs. ordering information device output current output voltage junction temp. range package shipping ? ncp/ncv593xx 3.0 a 1.5 v ? 40 c to +125 c d2pak ? 3 (pb ? free) contact sales office ncp/ncv593xx 3.0 a 1.65 v ? 40 c to +125 c d2pak ? 3 (pb ? free) contact sales office ncp/ncv593xx 3.0 a 1.8 v ? 40 c to +125 c d2pak ? 3 (pb ? free) contact sales office ncp/ncv593xx 3.0 a 2.5 v ? 40 c to +125 c d2pak ? 3 (pb ? free) contact sales office ncp/ncv593xx 3.0 a 3.3 v ? 40 c to +125 c d2pak ? 3 (pb ? free) contact sales office ncp/ncv593xx 3.0 a 1.5 v ? 40 c to +125 c d2pak ? 5 (pb ? free) contact sales office ncp/ncv593xx 3.0 a 1.8 v ? 40 c to +125 c d2pak ? 5 (pb ? free) contact sales office ncp/ncv593xx 3.0 a 2.5 v ? 40 c to +125 c d2pak ? 5 (pb ? free) contact sales office ncp/ncv593xx 3.0 a 3.3 v ? 40 c to +125 c d2pak ? 5 (pb ? free) contact sales office ncp59302dsadjr4g 3.0 a adj ? 40 c to +125 c d2pak ? 5 (pb ? free) 800 / tape & reel ncv59302dsadjr4g 3.0 a adj ? 40 c to +125 c d2pak ? 5 (pb ? free) 800 / tape & reel ?for information on tape and reel specifications, including part orientation and tape sizes, please refer to our tape and reel packaging specifications brochure, brd8011/d.
