KEY FEATURES  
DESCRIPTION  
The LM385/385B Micropower Voltage  
References are two terminal bandgap reference  
diodes designed and optimized for accurate low  
power operation in portable and other power  
The LM385 family is available in fixed 1.2V  
and 2.5V reference values. Process and circuit  
design optimization provides for high accuracy  
with initial tolerance values of 1% for the  
LM385B-1.2, 2% for the LM385-1.2, 1.5% for  
the LM385B-2.5, and 3% for the LM385-2.5.  
Complementing their initial accuracy, the  
bandgap reference is temperature compensated  
to deliver 20ppm performance over the 0° to  
70°C operating temperature range.

the LX385/385B-1.2, and 20µA up to 20mA for  
the LM385/385B-2.5, giving designers a great  
deal of flexibility in optimizing power  
consumption, noise and ultimate application
