The CS8363 is a precision micropower dual voltage regulator with ENABLE and RESET.
The 3.3 V standby output is accurate within ±2% while supplying loads of 100 mA. Quiescent current is low, typically 140 A with a 300 mA load. CS8363 active RESET output monitors the 3.3 V standby output and is low during powerup and regulator dropout conditions.
The RESET circuit CS8363 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 with a typical dropout voltage of 400 mV. 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.
