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 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 3.3V 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 available in either an 8-pin SOIC

thermally enhanced package, ideal for space critical

applications, or a 5-pin TO-263 package.
