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 15A up to
20mA for the LM385/385B-1.2, and 20A
up to 20mA for the LM385/385B-2.5,
giving designers a great deal of flexibility
in optimizing power consumption, noise
and ultimate application performance. As
an added feature, the references output
impedance is extraordinarily low over the
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
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.
