Typical Application Circuit  
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 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.  
CMPWR150  
When V is restored to a level above the select threshold,  
the contCrCol signal for the external PMOS switch is disabled  
and the regulator is once again enabled.  
Simplified Electrical Schematic  
All the necessary control circuitry needed to provide a  
smooth and automatic transition between the supplies  
has been incorporated. This allows VCC 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.
