Product Description
The SmartORTM CMPWR130 is a low dropout
regulator that delivers up to 300mA of load current at a fixed 3.3V output. An internal threshold level (TYP 4.1V) is used to prevent the
regulator from being operated below dropout voltage. The device continuously monitors the input supply and will automatically disable the
regulator when VCC falls below the threshold level. When the
regulator is disabled, the control signal “Drive” (Active Low) i...
