LM185-1.2/LM285-1.2/LM385-1.2  
Micropower Voltage Reference Diode  
The LM185-1.2 is rated for operation over a −55˚C to 125˚C  
temperature range while the LM285-1.2 is rated −40˚C to  
85˚C and the LM385-1.2 0˚C to 70˚C. The LM185-1.2/  
LM285-1.2 are available in a hermetic TO-46 package and  
the LM285-1.2/LM385-1.2 are also available in a low-cost  
TO-92 molded package, as well as SO and SOT-23. The  
LM185-1.2 is also available in a hermetic leadless chip  
carrier package.  
General Description  
The LM185-1.2/LM285-1.2/LM385-1.2 are micropower  
2-terminal band-gap voltage regulator diodes. Operating  
over a 10µA to 20mA current range, they feature exception-  
ally low dynamic impedance and good temperature stability.  
On-chip trimming is used to provide tight voltage tolerance.  
Since the LM185-1.2 band-gap reference uses only transis-  
tors and resistors, low noise and good long term stability  
result.  
Features  
Careful design of the LM185-1.2 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.

n 2.5V device and adjustable device also available

The extremely low power drain of the LM185-1.2 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.
