CS8361

5.0 V Dual Micropower Low Dropout Regulator with ENABLE and RESET

ON Semiconductor 

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.
