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 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 LM-185-2.5 band-gap reference uses only transis-  
tors and resistors, low noise and good long term stability  
result.  
Further, the wide operating current allows it to replace older  
references with a tighter tolerance part. For applications re-  
quiring 1.2V see LM185-1.2.

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. The LM185-25  
is also available in a hermetic leadless chip carrier package.  
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 pur-  
pose analog circuitry with battery life approaching shelf life.
