CS5201-1
1A Adjustable Linear Regulator
Description
The CS5201-1 linear regulator
provides 1A with an output
voltage accuracy of ±1%. The
device uses two external resis-
tors to set the output voltage
within a 1.25V to 5.5V range.
This regulator is intended for
use as a post regulator and
microprocessor supply. The fast
loop response and low dropout
voltage make this regulator
ideal for applications where low
voltage operation and good
transient response are impor-
tant.
The circuit is designed to oper-
ate with dropout voltages less
than 1.2V at 1A output current.
Device protection includes over-
current and thermal shutdown.
The CS5201 is pin compatible
with the LT1086 family of linear
regulators.
The regulator is available in
TO-220, surface mount D², and
SOT-223 packages.
