Adjustable Micropower Voltage References  
analog circuitry with battery life approaching shelf life. Fur-  
ther, the wide operating current allows it to replace older  
references with a tighter tolerance part.  
General Description  
The LM185/LM285/LM385 are micropower 3-terminal ad-  
justable band-gap voltage reference diodes. Operating from  
1.24 to 5.3V and over a 10µA to 20mA current range, they  
feature exceptionally low dynamic impedance and good tem-  
perature 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.  
The LM185 is rated for operation over a −55˚C to 125˚C  
temperature range, while the LM285 is rated −40˚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 pack-  
age, while the LM285/LM385 are available in a low-cost  
TO-92 molded package, as well as S.O.  
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.  
Features  
n Adjustable from 1.24V to 5.30V  
n Operating current of 10µA to 20mA  
n 1% and 2% initial tolerance  
n 1dynamic impedance  
n Low temperature coefficient  
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
