CS8135
5V, 5V Low Dropout Dual Regulator
with
/ENABLE
RESET
Description
Features
The CS8135 is a low dropout, high cur-
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.
ꢀ Two Regulated Outputs
Primary Output 5V
± 5%; 500mA
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.
Secondary Standby 5V
±5%; 10mA
ꢀ Low Dropout Voltage
The CS8135 is packaged in a 5 lead
TO-220.
(0.6V at 0.5A)
In automotive applications, the CS8135
and all regulated circuits are protected
from reverse battery installations, as
well as two-battery jumps. During line
ꢀ ON/OFF Control
NOTE: The CS8135 is compatible with
the LM2935.
