CS5201-3
CS5201-3
1A, 3.3V Fixed Linear Regulator
Description
The CS5201-3 linear regulator
provides a 1A@ 3.3V reference
at 1A with an output voltage
accuracy of ±1.5%.
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.
The maximum quiescent current
is only 10mA at full load.
Device protection includes over-
current and thermal shutdown.
The CS5201-3 is pin compatible
with the LT1086 family of linear
regulators.
The regulator is available in
TO-220, surface mount D
2
, and
SOT-223 packages.
