GENERAL DESCRIPTION

The ADR1500 is a low cost, 2-terminal (shunt), precision band

gap reference. It provides an accurate 1.2875 V output for input

currents between 50 μA to 10 mA.

The low minimum operating current makes the ADR1500 ideal

for use in battery-powered 3 V or 5 V systems. However, the

wide operating current range means the ADR1500 is extremely

versatile and suitable for use in a wide variety of high current

applications.

The ADR1500 is available in the tiny SC70 package and is

specified over the −40°C to +85°C operating temperature range.
