GM6603 Datasheet, PDF (1/11 Pages) List of Unclassifed Manufacturers – 3.0A PRECISION LINEAR REGULATORS

Description
GM6603 of positive adjustable and fixed regulators are de-
signed to provide 3.0A output with low dropout voltage per-
formance.
On-chip trimming adjusts the reference voltage to 2.0%. To
work in post regulators or microprocessor power supplies
where low voltage operation and fast transient response
are required.
Device includes over-current protection and thermal shut-
down protection as well.
Pin-to-pin compatible with LT1085 family of regulators,
GM6603 is available in TO-252, TO-220, and surface-
mount TO-263 packages.
