DESCRIPTION
The LM385 is micropower 3-terminal adjustable
band-gap voltage reference. Operating from
1.24V to 5.3V and over 10
μ
A to 20mA current
range. They feature exceptionally low dynamic
impedance and good temperature stability. On-
chip trimming is used to achieve tight voltage
tolerance. Since the LM385 band-gap reference
uses only transistors and resistors, low noise
and good longterm stability result.
Careful design of the LM385 has made the de-
vice tolerant of capacitive loading, making it
easy to use in almost any reference application.
The wide dynamic operating range allows its
use with widely varying supplies with excellent
regulation.
The extremely low power drain of the LM385
makes it useful for micropower circuitry. This
voltage reference can be used to make portable
meters, regulators or general purpose analog
circuitry with battery life approaching shelf life.
Further, the wide operating current allows it to
replace older references with a tighter tolerance
part.
