GENERAL DESCRIPTION

The ADR380 and ADR381 are precision 2.048 V and 2.500 V

band gap voltage references featuring high accuracy, high stabil-

ity, and low-power consumption in a tiny footprint. Patented

temperature drift curvature correction techniques minimize

nonlinearity of the voltage change with temperature. The wide

operating range and low power consumption make them ideal

for 3 V to 5 V battery-powered applications.

The ADR380 and ADR381 are micropower, low dropout

voltage (LDV) devices that provide a stable output voltage from

supplies as low as 300 mV above the output voltage. They are

specified over the industrial (–40

°C to +85°C) temperature

range. ADR380/ADR381 is available in the tiny 3-lead SOT-23

package.
