GM6615X 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.

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).
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
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_IN if it is not required for ON/OFF
control. The GM66150 s er i es is available in
3-pin and 5-pin TO-220 and surface mount
SOT-223 and TO-263 packages.
