ULTRA DROPOUT POSITIVE VOLTAGE REGULATOR Power Management
GM6251's combine high accuracy with very power consumption, providing high output current even when application requires extremely input-output voltage differential. GM6251's include precision voltage reference, error correction circuit, over-temperature protection, current limited output driver. Fast transient response load variations provides excellent stability under dynamic load conditions. GM6251's come SOT-25 (150mW), SOT-89 (500mW) TO-92 packages.
Features
Maximum output current 250mA (within maximum power dissipation) Output voltage: from 6.0V 0.1V increments Output voltage CMOS power consumption, typically 1.0µA VOUT 5.0V Input stability typically 0.2%/ Ultra-low dropout voltage 0.38V IOUT 200mA VOUT 5.0V Small input/ output differential: 0.4V 160mA (VOUT 3.3V) SOT-25 (150mW), SOT-89 (500mW) TO-92 packages

DIRECTIONS
Notes Please this within stipulated absolute maximum ratings liable malfunction outside such parameters. There possibility theat oscillation occur result impedance present between power supply IC's input. Where impedance more, please capacitor (CIN) least 1µF. With large output current, operations stabilised increasing capacitor size (CIN). small capacitor size (CL) increased, there possibility oscillation input impedance. such cases, operations stabilised either increasing size decreasing size Please ensure that output current (IOUT) less than (VIN VOUT) does exceed stipulated continuous total power dissipation value (Pd) package.
