CS8363
3.3 V Dual Micropower
Regulator with ENABLE and
RESET
The CS8363 is a precision Micropower dual voltage regulator with ENABLE and RESET.
The 3.3 V standby output is accurate within −2%, +2.4% while supplying loads of 100 mA. Quiescent current is low, typically 140 mA with a 300 mA load. The active RESET output monitors the 3.3 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 3.3 V standby output through an external adjust lead, and can supply loads of 250 mA. The logic level lead ENABLE 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 CS8363 makes it not only well suited for automotive microprocessor applications, but for any battery powered microprocessor applications.
