CS5207-1
CS5207-1
7A Adjustable Linear Regulator
Description
The CS5207-1 linear regulator pro-
vides 7A at adjustable voltages
with an accuracy of ±1.5%. Two
external resistors are used to set the
output voltage within a 1.25V to
13V range.
The regulator is intended for use as
post regulator and microprocessor
supply. The fast loop response and
low dropout voltage make this reg-
ulator ideal for applications 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 regulator is fully protected
against overload conditions with
protection circuitry for Safe
Operating Area (SOA), overcurrent
and thermal shutdown.
The regulator is available in a
TO-220 package. A 3.3V, fixed ver-
sion is also available. Please consult
factory for more information.
