LM385-2.5
Micropower Voltage Reference Diode
General Description
The LM385-2.5 are micropower
2-terminal band-gap voltage regulator diodes. Operating
over a 20 µA 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.
