DESCRIPTION  
KEY FEATURES  
GUARANTEED 1% INITIAL ACCURACY  
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 sensitive  
systems. Operating currents are  
guaranteed from as low as 15µA up to  
20mA for the LM385/385B-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  
andultimateapplicationperformance. As  
an added feature, the references output  
impedanceisextraordinarilylowoverthe  
entire operating range of quiescent  
currents. This enables an extremely wide  
dynamic load range with little effect on  
the overall reference accuracy.  
The LM385 family is available in fixed  
(LM385B-1.2)  
GUARANTEED 2.5% INITIAL ACCURACY  
(LM385-1.2)  
GUARANTEED 1.5% INITIAL ACCURACY  
(LM385B-2.5)  
GUARANTEED 3% INITIAL ACCURACY  
(LM385-2.5)  
p GUARANTEED 20µA OPERATING CURRENT  
p LOW TEMPERATURE COEFFICIENT  
1.2V and 2.5V reference values. Process  
and circuit design optimization provide  
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 LM385 family from Linfinity is a  
pin-for-pin replacement for the LM385/  
385B family of voltage references.
