ZXRE4041  
SOT23 MICROPOWER 1.225V VOLTAGE REFERENCE  
SUMMARY  
DESCRIPTION  
The ZXRE4041 is a bandgap circuit designed to achieve a precision  
m icropower voltage reference of 1.225 volts. The device is available in the  
sm all outline SOT23 surface m ount package which is ideal for applications  
where space saving is im portant.  
SOT23 tolerance is available to 0.5% C grade for precision applications.  
Excellent perform ance is m aintained over the 30␮A to 12m A operating  
current range with a typical tem perature coefficient of only 20ppm /°C. The  
device has been designed to be highly tolerant of capacitive loads so  
m aintaining excellent stability.  
This device offers a SOT23 pin for pin com patible alternative to LM4041  
voltage references.
