CS5205-1,-3,-5
5A Adjustable, and 3.3V
and 5V Fixed Linear Regulators
Description
Features
The CS5205-X series of linear regu-
lators provides 5A at adjustable
and fixed voltages with an accura-
cy of ±1% and ±2% respectively.
The adjustable version uses two
external resistors to set the output
voltage within a 1.25V to 13V
range.
The regulators are intended for use
as post regulators and microproces-
sor supplies. The fast loop response
and low dropout voltage make
these regulators ideal for applica-
tions where low voltage operation
and good transient response are
important.
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 regulators are fully protected
against overload conditions with
protection circuitry for Safe
Operating Area (SOA), overcurrent
and thermal shutdown.
The CS5205-X is pin compatible
with the LT1084 family of linear
regulators but has lower dropout
voltage.
The regulators are available in TO-
220 and surface mount D² packages.
