CS5206 -1,-3,-5
6A Adjustable, and Fixed 3.3V
and 5V Linear Regulators
Description
The CS5206 -X series of linear regu-
lators provides 6A at adjustable
and fixed voltages of 3.3V and 5V
with an accuracy 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 regulators are available in TO-
220 and surface mount D
2
packages.
