Description

The ADR370 is a low cost, 3-terminal (series) band-gap voltage reference featuring high accuracy, high stability, and low power consumption packaged in a tiny 3-lead SOT-23 package. Precise matching and thermal tracking of on-chip components, as well as patented temperature drift curvature correction design techniques, have been employed to ensure that the ADR370 provides an accurate 2.048 V output.

This micropowered, low dropout voltage device will source or sink up to 5 mA of load current while providing a stable 2.048 V output. The compact footprint, high accuracy, and an operating range of 2.3 V to 12 V make the ADR370 ideal for use in 3 V and 5 V systems where there may be wide variations in supply voltage and a need to minimize power dissipation.

The ADR370 is offered in A and B grades; all devices are specified over the extended industrial range of 40°C to +125°C.
