3 Description
The LMx85-2.5 and LM385B are micropower, twoterminal, band-gap voltage references that operate over a 20-μA to 20-m A current range and feature exceptionally low dynamic impedance and good temperature stability. On-chip trimming provides tight voltage tolerance. The band-gap reference for these devices has low noise and long-term stability.
The design makes these devices exceptionally tolerant of capacitive loading and, thus, easier to use in most reference applications. The wide dynamic operating temperature range acmodates varying current supplies, with excellent regulation.
The extremely low power drain...
