description  
These micropower two-terminal band-gap voltage references operate over a 20-µA to 20-mA current range and  
feature exceptionally low dynamic impedance and good temperature stability. On-chip trimming provides tight  
voltage tolerance. The band-gap reference for these devices has low noise and long-term stability.  
The design makes these devices exceptionally tolerant of capacitive loading and thus, easier to use in most  
reference applications. The wide dynamic operating temperature range accommodates varying current  
supplies with excellent regulation.  
The extremely low power drain of this series makes them useful for micropower circuitry. These voltage  
references can make portable meters, regulators, or general-purpose analog circuitry with battery life  
approaching shelf life. The wide operating current range allows them to replace older references with  
tighter-tolerance parts.  
The LM285-2.5 is characterized for operation from –40°C to 85°C. The LM385-2.5 and LM385B-2.5 are  
characterized for operation from 0°C to 70°C.
