DESCRIPTION
The LM185-2.5 are micropower 2-terminal band-gap
voltage regulator diodes. Operating over a 20 μA to
20 mA current range, they feature exceptionally low
dynamic impedance and good temperature stability.
On-chip trimming is used to provide tight voltage
tolerance. Since the LM185-2.5 band-gap reference
uses only transistors and resistors, low noise and
good long term stability result.
Careful design of the LM185-2.5 has made the device
exceptionally 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 LM185-2.5
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. For applications requiring
1.2V see LM185-1.2.
