LM185-1.2QML
Micropower Voltage Reference Diode
General Description
The LM185-1.2 is a micropower 2-terminal band-gap voltage
regulator diodes. Operating over a 10A to 20mA current
range, it features exceptionally low dynamic impedance and
good temperature stability. On-chip trimming is used to pro-
vide tight voltage tolerance. Since the LM185-1.2 band-gap
reference uses only transistors and resistors, low noise and
good long term stability result.
Careful design of the LM185-1.2 has made the device ex-
ceptionally tolerant of capacitive loading, making it easy to
use in almost any reference application. The wide dynamic
operating range allows its use with widely varying supplies
with excellent regulation.
The extremely low power drain of the LM185-1.2 makes it
useful for micropower circuitry. This voltage reference can be
used to make portable meters, regulators or general purpose
analog circuitry with battery life approaching shelf life.
Further, the wide operating current allows it to replace older
references with a tighter tolerance part.
