Micropower Voltage Reference Diode
General Description
The
LM385-2.5
are
micropower
2-terminal band-gap voltage regulator diodes. Operating
over a 20 A to 20 mA current range, they feature exception-
ally low dynamic impedance and good temperature stability.
On-chip trimming is used to provide tight voltage tolerance.
