Description

GM66102 of positive fixed and adjustable regulators is de-

signed to provide up to 1A output with high current, high ac-

curacy, 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, and loads, these devices are also useful in

lower current, extremely low dropout-critical systems,

where their minimal dropout voltage and ground current val-

ues are important characteristics.

GM66102 is fully protected against overcurrent, reversed

input polarity (or reversed battery connection), reversed

lead insertion, over-temperature operation, and transient

voltage spikes (positive or negative). GM66102 is available

in TO-220, SOT-223, TO-252 and TO-263 packages.
