GENERAL 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.
