DESCRIPTION  
The UTC 81CXXX and 81NXXX series are good  
SOT-89  
TO-92  
performance voltage detector and manufactured by CMOS  
technologies with highly accurate, low power consumption.  
A delay circuit is built-in to each detector, therefore,  
peripherals are unnecessary and high density mounting is  
possible. Detect voltage is extremely accurate with minimal  
temperature drift. Both CMOS and N-channel open drain  
output configurations are available.

Note: The power consumption during power-start to output being stable (release operation) is 2 µA greater than it is  
after that period (completion of release operation) because of delay circuit through current.
