LM185-2.5/LM285-2.5/LM385-2.5
Micropower Voltage Reference Diode
General Description
The LM185-2.5/LM285-2.5/LM385-2.5 are micropower
2-terminal band-gap voltage regulator diodes. Operating
over a 20 µA to 20 mA current range, they feature excep-
tionally low dynamic impedance and good temperature sta-
bility. On-chip trimming is used to provide tight voltage toler-
ance. Since the LM-185-2.5 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 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 LM185-2.5 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. Fur-
ther, the wide operating current allows it to replace older
references with a tighter tolerance part. For applications
requiring 1.2V see LM185-1.2.
The LM185-2.5 is rated for operation over a −55˚C to 125˚C
temperature range while the LM285-2.5 is rated −40˚C to
85˚C and the LM385-2.5 0˚C to 70˚C. The LM185-2.5/
LM285-2.5 are available in a hermetic TO-46 package and
the LM285-2.5/LM385-2.5 are also available in a low-cost
TO-92 molded package, as well as S.O. and SOT-23. The
LM185-2.5 is also available in a hermetic leadless chip
carrier package.

Note 4: Parameters identified with boldface type apply at temperature extremes. All other numbers apply at TA = TJ = 25˚C.
Note 5: Guaranteed and 100% production tested.
Note 6: Guaranteed, but not 100% production tested. These limits are not used to calculate average outgoing quality levels.
Note 7: The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures between the operating TMAX
and TMIN, divided by TMAX–TMIN. The measured temperatures are −55˚C, −40˚C, 0˚C, 25˚C, 70˚C, 85˚C, 125˚C.
Note 8: A military RETS electrical specification available on request.
