LM185/LM285/LM385
Adjustable Micropower Voltage References
General Des cription
The LM185/LM285/LM385 are micropower 3-terminal adjustable
band-gap voltage reference diodes. Operating from
1.24 to 5.3V and over a 10 mA 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 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.
The LM185 is rated for operation over a b55§C to 125§C
temperature range, while the LM285 is rated b40§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 package,
while the LM285/LM385 are available in a low-cost
TO-92 molded package, as well as S.O.
