GM6603
3.0A PRECISION LINEAR REGULATORS
Power Management
Description
The GM6603 series of positive adjustable and fixed regula-
tors are designed to provide 3.0A output with low dropout
voltage performance.
On-chip trimming adjusts the reference voltage to 2.0%.
Put them to work in post regulators or microprocessor
power supplies where low voltage operation and fast tran-
sient response are required.
Device includes over-current protection and thermal shut-
down protection as well.
Pin-to-pin compatible with the LT1085 family of regulators,
the GM6603's are available in TO-252, TO-220 and sur-
face-mount TO-263 packages.
