FEATURES  
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.

Adjustable from 1.24V to 5.30V  
Operating Current of 10μA to 20mA  
1% and 2% Initial Tolerance  
1Ω Dynamic Impedance  
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 analog circuitry with battery life  
approaching shelf life. Further, the wide operating  
current allows it to replace older references with a  
tighter tolerance part.  
Low Temperature Coefficient  
DESCRIPTION  
The LM185/LM285/LM385 are micropower 3-terminal  
adjustable 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 temperature 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 package and a  
LCCC package, while the LM285/LM385 are  
available in a low-cost TO-92 package, as well as  
SOIC.
