3 Description
The LMx85-2.5 and LM385B are micropower, two-
terminal, band-gap voltage references that operate
over a 20-μA to 20-mA current range and feature
exceptionally low dynamic impedance and good
temperature stability. On-chip trimming provides tight
voltage tolerance. The band-gap reference for these
devices has low noise and long-term stability.
The design makes these devices exceptionally
tolerant of capacitive loading and, thus, easier to use
in most reference applications. The wide dynamic
operating temperature range accommodates varying
current supplies, with excellent regulation.
The extremely low power drain of this series makes
these devices useful for micropower circuitry. These
voltage references can be used to make portable
meters, regulators, or general-purpose analog
circuitry, with battery life approaching shelf life. The
wide operating current range of these voltage
references allows them to replace older references
with tighter-tolerance parts.
