Product Description
California Micro Devices SmartOR
TM
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
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
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
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.
