GM6251
ULTRA - LOW DROPOUT POSITIVE VOLTAGE
REGULATOR Power Management
Description
The GM6251's combine high accuracy with very low power consumption, providing high output current even when the application requires extremely low input-output voltage differential. The GM6251's include a precision voltage reference, an error correction circuit, over-temperature protection, and a current limited output driver. Fast transient response to load variations provides excellent stability under dynamic load conditions. The GM6251's come in SOT-25 (150mW), SOT-89 (500mW) and TO-92 packages.
Features
Maximum output current 250mA (within maximum power dissipation) Output voltage: from 1.8 V to 6.0V in 0.1V increments Output voltage ±2% CMOS low power consumption, typically 1.0µA at VOUT = 5.0V Input stability typically 0.2%/ V Ultra-low dropout voltage 0.38V @ IOUT = 200mA at VOUT = 5.0V Small input/ output differential: 0.4V at 160mA (VOUT = 3.3V) SOT-25 (150mW), SOT-89 (500mW) and TO-92 packages
