LM185/LM285/LM385  
Adjustable Micropower Voltage References  
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 tem-  
perature 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 package, while the  
LM285/LM385 are available in a low-cost TO-92 molded  
package, as well as S.O.  
Features  
Careful design of the LM185 has made the device tolerant of  
capacitive loading, making it easy to use in almost any refer-  
ence application. The wide dynamic operating range allows  
its use with widely varying supplies with excellent regulation.  
Adjustable from 1.24V to 5.30V  
Operating current of 10μA to 20mA  
1% and 2% initial tolerance  
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 ana-  
log circuitry with battery life approaching shelf life. Further, the
