LM185-1.2/LM285-1.2/LM385-1.2  
Micropower Voltage Reference Diode  
General Description  
b
55 C to  
The LM185-1.2/LM285-1.2/LM385-1.2 are micropower  
2-terminal band-gap voltage regulator diodes. Operating  
over a 10 mA to 20 mA current range, they feature excep-  
tionally low dynamic impedance and good temperature sta-  
bility. On-chip trimming is used to provide tight voltage toler-  
ance. Since the LM185-1.2 band-gap reference uses only  
transistors and resistors, low noise and good long term sta-  
bility result.  
The LM185-1.2 is rated for operation over a  
125 C temperature range while the LM285-1.2 is rated

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 S.O. The LM185-  
1.2 is also available in a hermetic leadless chip carrier pack-  
age.  
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.

Low temperature coefficient  
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 pur-  
pose analog circuitry with battery life approaching shelf life.  
Low voltage referenceÐ1.235V  
2.5V device and adjustable device also available  
Ð LM185-2.5 series and LM185 series, respectively  
Further, the wide operating current allows it to replace older  
references with a tighter tolerance part.
