CS5203-1
3A Adjustable Linear Regulator
Description
The CS5203-1 linear regulator pro-
vides 3A at adjustable output volt-
ages with an accuracy of ±1.5%.
The device uses two external resis-
tors to set the output voltage with-
in a 1.25V to 5.5V range.
The regulator is intended for use as
a post regulator and microproces-
sor supply. The fast loop response
and low dropout voltage make this
regulator ideal for applications
where low voltage operation and
good transient response are impor-
tant.
The circuit is designed to operate
with dropout voltage less than 1.4V
at 3A output current. Device pro-
tection includes overcurrent and
thermal shutdown.
The CS5203-1 is pin compatible
with the LT1085 family of linear
regulators but has lower dropout
voltage.
The regulator is available in TO-220
and surface mount D² packages.
