CS5205A-1
5A Adjustable Linear Regulator
Description
The CS5205A-1 linear regulator
provides 5A at an adjustable volt-
age with an accuracy of ±1%. Two
external resistors are used to set the
output voltage within a 1.25V to
13V 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 voltages as low as 1V
depending on the output current
level. The maximum quiescent cur-
rent is only 10mA at full load.
The regulator is fully protected
against overload conditions with
protection circuitry for Safe
Operating Area (SOA), overcurrent
and thermal shutdown.
The CS5205A-1 is pin compatible
with the LT1084 family of linear
regulators but has lower dropout
voltage.
The regulator is available in TO-220
and surface mount D² packages.
