CS8135
5V, 5V Low Dropout Dual Regulator
with RESET/ENABLE
Description
Features
The CS8135 is a low dropout, high cur-
rent, dual 5V linear regulator. The sec-
ondary 5V/10mA output is often used
for powering systems with standby
memory. Quiescent current drain is
less than 3mA when supplying 10mA
loads from the standby regulator.
In automotive applications, the CS8135
and all regulated circuits are protected
from reverse battery installations, as
well as two-battery jumps. During line
transients, such as a 60V load dump,
the 500mA output will automatically
shut down the primary output to pro-
tect both internal circuits and the load.
The standby regulator will continue to
power any standby load.
The CS8135 is packaged in a 5 lead
TO-220.
NOTE: The CS8135 is compatible with
the LM2935.
