GM66150 Series

1.5A ULTRA LOW DROPOUT VOLTAGE

REGULATORS

Description

Features

The GM66150 series of positive fixed and

adjustable regulators is designed to provide up

to 1.5A output with high current, high accuracy,

and extremely low dropout voltage performance.

These regulators feature 300 to 350mV (full

load) dropout voltages, and very low ground

current. Although designed for high current loads,

these devices are also useful in lower current,

extremely low dropout critical systems, where the

minimal dropout voltage and ground current

values are important characteristics.

Ultra Low Dropout Voltage of 350mV @

1.5A with Low Ground Current

Fixed and Adjustable Voltage Versions

Output Current up to 1.5A

Guaranteed 1% Accurate Tolerance

Extremely Fast Transient Response

Reverse-battery Protection

"Load Dump" Protection

TheGM66150 is fully protected against over

current, reversed input polarity (or reversed

battery connection), reversed lead insertion, over

temperature operation, and transient voltage

spikes (positive or negative).

Zero-Current shutdown mode(5-pin

versions) Error flag signals output

out-of-regulation (5-pin versions)

Five lead fixed voltage versions feature logic

level ON/OFF control and an error flag which

signals whenever the output falls out of

regulation.

For GM66151 and GM66152, the ENABLE pin

may be tied to V_INif it is not required for ON/OFF

control. The GM66150 series is available in

3-pin and 5-pin TO-220 and surface mount

SOT-223 and TO-263 packages.
