LM185/LM285/LM385 Adjustable Micropower Voltage Reference
February 2005
LM185/LM285/LM385
Adjustable Micropower Voltage References
General Description
The LM185/LM285/LM385 are micropower 3-terminal ad-
justable 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 tem-
perature 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. Fur-
ther, the wide operating current allows it to replace older
references with a tighter tolerance part.
The LM185 is rated for operation over a −55˚C to 125˚C
temperature range, while the LM285 is rated −40˚C to 85˚C
and the LM385 0˚C to 70˚C. The LM185 is available in a
hermetic TO-46 package and a leadless chip carrier pack-
age, while the LM285/LM385 are available in a low-cost
TO-92 molded package, as well as S.O.
