ADR510ARTZ-R2

Designed for space critical applications, the ADR510 is a low voltage (1.000 V), precision shunt - mode voltage reference in an ultracompact (3 mm×3 mm) SOT - 23 - 3 package. The ADR510 features low temperature drift (70 ppm/°C), high accuracy (±0.35%), and ultralow noise (4 μV p - p) performance. The ADR510 advanced design eliminates the need for an external capacitor, yet it is stable with any capacitive load. The minimum operating current increases from 100 μA to a maximum of 10 mA. This low operating current and ease of use make the ADR510 ideally suited for handheld battery - powered applications. A TRIM terminal is available on the ADR510 to provide adjustment of the output voltage over ±0.5% without affecting the temperature coefficient of the device. This feature provides users with the flexibility to trim out any system errors.
