Features

Description

Fixed and Adjustable Voltage Versions

Output Current up to 1.5A

Low Dropout Voltage 350mV @ 1.5A

Low Ground Current

The GM66150 series of positive fixed and adjustable regu-

lators 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 their minimal dropout voltage and

ground current values are important characteristics.

Accurate 1% Guaranteed Tolerance

Extremely Fast Transient Response

Reverse-battery Protection

"Load Dump" Protection

Zero-Current shutdown mode(5-pin versions)

Error flag signals output out-of-regulation

(5-pin versions)

The GM66150 is fully protected against overcurrent, re-

versed input polarity (or reversed battery connection), re-

versed lead insertion, over-temperature operation, and tran-

sient voltage spikes (positive or negative).

Application

Five pin fixed voltage versions feature logic level ON/OFF

control and an error flag which signals whenever the output

falls out of regulation.

High Efficiency Linear Regulators

Post Regulators for Switching Supplies

High Efficiency "Green" Computer

Systems

On the GM66151 and GM66152, the ENABLE pin may be

tied to V if it is not required for ON/OFF control.

The GM66150 is available in 3-pin and 5-pin TO-220 and

surface mount TO-263 packages.
