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.
