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.
