CS5207A-1
CS5207A-1
7A LDO 3-Pin Adjustable Linear Regulator
Description
The CS5207A-1 linear regulator pro-
vides 7A at adjustable voltages
from 1.25V to 5V. This adjustable
device requires two external resis-
tors to set the output voltage and
provide the minimum load current
for proper regulation.
This regulator is intended for use as
a 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
1.0V at 7A.
This regulator is protected against
overload conditions with overcur-
rent and thermal shutdown
protection circuitry.
The CS5207A-1 is pin compatible
with the LT1584 family of linear
regulators but has lower dropout
voltage and faster transient
response.
This regulator is available in a
TO-220 package.
