GENERAL DESCRIPTION
The ADR380 and ADR381 are precision 2.048 V and 2.500 V
band gap voltage references featuring high accuracy, high
stability, 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. The ADR380/ADR381 are available in the tiny 3-lead
SOT-23 package.
