GM6250
ULTRA-LOW DROPOUT POSITIVE VOLTAGE REGULATOR
Maximum output current 250mA (within maximum power dissipation) Output voltage: from 6.0V 0.1V increments Output voltage CMOS power consumption, typically 2.0µA VOUT=5.0V Input stability typically 0.2%/V Ultra-low dropout voltage (0.12V IOUT 100mA, VOUT 5.0V; 0.38V IOUT 200mA VOUT 5.0V SOT-23 (150mW), SOT-89 (500mW) TO-92 packages
GM6250's combine high accuracy with very power consumption, providing high output current even when application requires extremely input-output voltage differential. GM6250'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. GM6250's come SOT-23 (150mW), SOT-89 (500mW) TO-92 packages. Applications: Palmtops Portable Cameras Video Recorders Battery Powered Equipment Reference Voltage Sources
