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 dif-

ferential.

The GM6251's include a precision voltage reference, an er-

ror 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
