Description
GM6605 series of positive adjustable and fixed regulators
is designed to provide 5A output with low dropout voltage
performance. On-chip trimming adjusts the reference volt-
age with an accuracy of ±1% for adjustable, and ±2% for
fixed voltage versions. To work in post regulators or micro-
processor power supplies, which where low voltage opera-
tion and fast transient response are required. Device in-
cludes over-current protection and thermal shutdown pro-
tection as well.
GM6605 is available in TO-220 and surface-mount TO-263
packages.
