CMPWR150
500 mA/3.3 V SmartOR t Power
Regulator
Product Description
The CMPWR150 is a low dropout regulator that delivers up to
500 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,
the control signal “Drive” (Active Low) is enabled, which allows an
external PMOS switch to power the load from an auxiliary 3.3 V
supply.
When V CC is restored to a level above the select threshold, the
control signal for the external PMOS 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.
The CMPWR150 is housed in an 8 ? pin SOIC thermally enhanced
package which is ideal for space critical applications. The
CMPWR150 is available with RoHS compliant lead ? free finishing.
