CS8361
5V Dual Micropower Low Dropout
Regulator with ENABLE and RESET
Description
Features
The CS8361 is a precision micro-
power dual voltage regulator with
ENABLE RESET
The second output tracks the 5V
standby output through an external
adjust lead, and can supply loads
of 250mA with a typical dropout
voltage of 400mV. The logic level

.
The 5V standby output is accurate
within ±2% while supplying loads
of 100mA and has a typical
dropout voltage of 400mV.
Quiescent current is low, typically
140µA with a 300µA load. The

this tracking regulator output.
■ Low Dropout Voltage
(0.4V at rated current)
Both outputs are protected against
overvoltage, short circuit, reverse
battery and overtemperature condi-
tions. The robustness and low qui-
escent current of the CS8361 makes
it not only well suited for automo-
tive microprocessor applications,
but for any battery powered micro-
processor applications.
