• 8-pin Narrow SOIC package  
Product Description  
The California Micro Devices’ SmartORTM CMPWR100 is  
a low dropout regulator that delivers up to 200mA 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 automati-  
cally disable the regulator when VCC 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 auxil-  
iary 3.3V supply.  
When VCC is restored to a level above the select thresh-  
old, 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 VCC to be dynami-  
cally switched without loss of output voltage.  
A logic output signal, Drive, is active LOW whenever the  
internal regulator is disabled.
