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.
„
On-chip trimming adjusts the reference voltage with „
an accuracy of 2%. Besides the features
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.
„
„
GM6605 is available in TO-220 and surface-mount TO-
252 and TO-263 packages.
