The CS8361 is a precision micro-power dual voltage regulator with ENABLEbar and RESETbar. 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 RESETbar output monitors the 5V standby output and holds the RESETbar line low during power-up and regulator dropout conditions. The RESETbar 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 ENABLEbar 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.
