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 and RESET.
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
active RESET output monitors the
5V standby output and holds
the RESET line low during power-
up and regulator dropout condi-
tions. The RESET circuit includes
hysteresis and is guaranteed to
operate correctly with 1V on the
standby output.
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
ENABLE lead is used to control
this tracking regulator output.
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.
