GM6603
3.0A LOW DROPOUT
PRECISION REGULATOR
Description
Features
GM6603 series of positive adjustable and fixed
regulators is designed to provide 3A output current
with low dropout voltage performance.
Adjustable or Fixed Output
Output Current of 3.0A
On-chip trimming adjusts the reference voltage with
an accuracy of ±2%. Besides the features
Low Dropout, 1.15V max at 3A
Output Current
mentioned, GM6603 works well in post regulators
or micro-processor power supplies where low
voltage operation and fast transient response are
required. GM6603 includes over current protection
and thermal shutdown protection as well.
0.04% Line Regulation
0.2 % Load Regulation
Current Limit Protection
100% Thermal Limit Burn-In
Fast Transient Response
GM6605 is available in TO-220 and surface-mount TO-
252 and TO-263 packages.
