CS5208-1
CS5208-1
8A LDO 3-Pin Adjustable Linear Regulator
Description
The CS5208-1 linear regulator pro-
vides 8A at adjustable voltages
from 1.25V to 4.5V. 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 micropro-
cessor supply. The fast loop
response and low dropout voltage
make this regulator ideal for appli-
cations where low voltage opera-
tion and good transient response
are important.
The circuit is designed to operate
with dropout voltages as low as
1.0V at 8A.
The regulator is protected against
overload conditions with overcur-
rent and thermal shutdown
protection circuitry.
The regulator is available in a
TO-220 package.
