CS8361 Datasheet, PDF (1/8 Pages) Cherry Semiconductor Corporation – 5V Dual Micropower Low Dropout Regulator with ENABLE and RESET

CS8361
5.0 V Dual Micropower
Low Dropout Regulator
with ENABLE and RESET
The CS8361 is a precision Micropower dual voltage regulator with
ENABLE and RESET.
The 5.0 V standby output is accurate within ±2% while supplying
loads of 100 mA and has a typical dropout voltage of 400 mV.
Quiescent current is low, typically 140 mA with a 300 mA load. The
active RESET output monitors the 5.0 V standby output and is low
during power−up and regulator dropout conditions. The RESET
circuit includes hysteresis and is guaranteed to operate correctly with
1.0 V on the standby output.
The second output tracks the 5.0 V standby output through an
external adjust lead, and can supply loads of 250 mA with a typical
dropout voltage of 400 mV. 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 conditions. The robustness and low
quiescent current of the CS8361 makes it not only well suited for
automotive microprocessor applications, but for any battery powered
microprocessor applications.
