Description
GM6251 combines high accuracy with very low power consumption, and provides high output current even when the application requires extremely low input-output voltage differential. GM6251 includes 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. GM6251 comes 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 1.0?A 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

Application

DIRECTIONS FOR USAGE
Notes on Usage 1. Please use this IC within the stipulated absolute maximum ratings as the IC is liable to malfunction outside of such parameters. 2. There is a possibility theat, oscillation may occur as a result of the impedance present between the power supply and the IC's input. Where impedance is 10W or more, please use a capacitor (CIN) of at least 1?F. With a large output current, operations can be stabilised by increasing capacitor size (CIN). If CIN is small and capacitor size (CL) is increased, there is a possibility of oscillation due to input impedance. In such cases, operations can be stabilised by either increasing the size of CIN or decreasing the size of CL. 3. Please ensure the output current (IOUT) is less than Pd ÷ (VIN - VOUT) and does not exceed the stipulated continuous total power dissipation value (Pd) for the package.
