GENERAL DESCRIPTION
The ADR01-EP is a 10.0 V band gap voltage reference featuring
high accuracy, high stability, and low power consumption. This
part is housed in a tiny TSOT package. The small footprint and
wide operating range make the ADR01-EP reference ideally
suited for general-purpose and space-constrained applications.
With an external buffer and a simple resistor network, the
TEMP terminal can be used for temperature sensing and
approximation. A TRIM terminal is provided on the device for
fine adjustment of the output voltage.
The ADR01-EP is a compact, low drift voltage reference that
provides an extremely stable output voltage from a wide supply
voltage range.
Additional application and technical information can be found
in the ADR01/ADR02/ADR03/ADR06 data sheet.
