GM6605
5.0A LOW DROPOUT
PRECISION REGULATOR
Description
GM6605 series of positive adjustable and fixed
regulators is designed to provide 5A output current
with low dropout voltage performance. On-chip
trimming adjusts the reference voltage with an
accuracy of
±1%
for adjustable, and
±2%
for fixed
output voltage versions. Besides the features
mentioned, GM6605 works well in post regulators
or micro-processor power supplies where low
voltage operation and fast transient response are
required. GM6605 includes over current protection
and thermal shutdown protection as well.
GM6605 is available in TO-220 and surface-mount TO-
263 packages.
