GM66150 Series
1.5A ULTRA LOW DROPOUT VOLTAGE
REGULATORS
Description
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).
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 ser ies is available in
3-pin and 5-pin TO-220 and surface mount
SOT-223 and TO-263 packages.
