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

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.
