DESCRIPTION
The LM185 are micropower 3-terminal adjustable
band-gap voltage reference diodes. Operating from
1.24 to 5.3V and over a 10μA to 20mA current range,
they feature exceptionally low dynamic impedance
and good temperature stability. On-chip trimming is
used to provide tight voltage tolerance. Since the
LM185 band-gap reference uses only transistors and
resistors, low noise and good long-term stability
result.
Careful design of the LM185 has made the device
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 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.
