LM285-2.5 Micropower Voltage Reference

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. The band-gap reference for these devices has low noise and long-term stability. The design makes t.
