GENERAL DESCRIPTION  
A TRIM terminal is available on the ADR512 to provide adjust-  
ment of the output voltage over Ϯ0.5% without affecting the  
temperature coefficient of the device. This feature provides  
users with the flexibility to trim out any system errors.  
Designed for space critical applications, the ADR512 is a low  
voltage (1.200 V), precision shunt-mode voltage reference in the  
ultracompact (3 mm ϫ 3 mm) SOT-23 package. The ADR512  
features low temperature drift (60 ppm/ЊC), high accuracy  
(Ϯ0.30%), and ultralow noise (4 ␮V p-p) performance.  
The ADR512’s advanced design eliminates the need for an  
external capacitor, yet it is stable with any capacitive load. The  
minimum operating current increases from a scant 100 ␮A to a  
maximum of 10 mA. This low operating current and ease of use  
make the ADR512 ideally suited for handheld battery-powered  
applications.
