LM285-2.5 - Micropower Voltage Reference

Description

The LMx85-2.5 and LM385B are micropower, twoterminal, band-gap voltage references that operate over a 20-μA to 20-mA current range and feature exceptionally low dynamic impedance and good temperature stability.

On-chip trimming provides tight voltage tolerance.

Features

  • 1 Operating Current Range 20 μA to 20 mA.
  • 1.5% and 3% Initial Voltage Tolerance.
  • Reference Impedance.
  • LM385 1 Ω Maximum at 25°C.
  • All Devices 1.5 Ω Maximum Over Full Temperature Range.
  • Very Low Power Consumption 2.
