Product Description California Micro Devices SmartORTM CMPWR150 is a low dropout
regulator that delivers up to 500mA of load current at a fixed 3.3V output. An internal threshold level (typically 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 ...
