CMPWR101
250 mA SmartOR t Regulator
with V AUX Switch
Product Description
The ON Semiconductor ’s SmartOR t CMPWR101 is a low dropout
regulator that delivers up to 250 mA of load current at a fixed 3.3 V
output. An internal threshold level (typically 4.1 V) 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 V CC falls below the threshold level. When the
regulator is disabled, a low impedance, fully integrated switch is
enabled which allows the output to be directly powered from an
auxiliary 3.3 V supply.
When V CC is restored to a level above the select threshold, the low
impedance switch is disabled and the regulator is once again enabled.
All the necessary control circuitry needed to provide a smooth and
automatic transition between the supplies has been incorporated. This
allows V CC to be dynamically switched without loss of output voltage.
An output logic signal, DRIVE, is active LOW whenever the
internal regulator is disabled.
The CMPWR101 is housed in a 8 ? pin SOIC package and is
available with RoHS compliant lead ? free finishing.
