GENERAL DESCRIPTION
Designed for space critical applications, the ADR510 is a low
voltage (1.000 V), precision shunt-mode voltage reference in the
ultracompact (3 mm ϫ 3 mm) SOT-23 package. The ADR510
features low temperature drift (70 ppm/ЊC), high accuracy
(Ϯ0.35%), and ultralow noise (4 V p-p) performance.
The ADR510’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 ADR510 ideally suited for hand-held battery-
powered applications.
A TRIM terminal is available on the ADR510 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.
