Micropower Voltage Reference Diode
LM185-1.2/LM285-1.2/LM385-1.2
Micropower V oltage Reference Diode
General DescriptionThe LM185-1.2/LM285-1.2/LM385-1.2 are micropower
2-terminal band-gap voltage regulator diodes. Operating
overa 10µAto 20mA current range, they feature exception-
ally low dynamic impedance and good temperature stability.
On-chip trimmingis usedto provide tight voltage tolerance.
Sincethe LM185-1.2 band-gap reference uses only transis-
tors and resistors, low noise and good long term stability
result.
Careful designof the LM185-1.2 has made the device ex-
ceptionally tolerantof capacitive loading, makingit easyto
usein almost any reference application. The wide dynamic
operating range allowsits use with widely varying supplies
with excellent regulation.
The extremely low power drainof the LM185-1.2 makesit
usefulfor micropower circuitry. Thisvoltagereference canbe
usedto make portable meters, regulatorsor general purpose
analog circuitry with batterylife approaching shelf life.
Further,the wide operating current allowsitto replace older
references witha tighter tolerance part.
The LM185-1.2is ratedfor operation overa −55˚Cto 125˚C
temperature range while the LM285-1.2is rated −40˚Cto
85˚C and the LM385-1.2 0˚Cto 70˚C. The LM185-1.2/
LM285-1.2 are availableina hermetic TO-46 package and
the LM285-1.2/LM385-1.2 are also availableina low-cost
TO-92 molded package,as wellas SO and SOT-23. The
LM185-1.2is also availableina hermetic leadless chip
carrier package.
Features ±1% and 2% initial tolerance Operating currentof 10µAto 20mA 1Ω dynamic impedance Low temperature coefficient Low voltage reference—1.235V 2.5V device and adjustable device also available LM185-2.5 series and LM185 series, respectively
