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 LX385/385B-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
current.
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 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 LM385 family from Linfinity is a pin-to-
pin replacement for the LM385/385B family of
voltage references.
