LM385/B

The LM385/B is micropower 3-terminal adjustable band-gap voltage reference. Operating from 1.24V to 5.3V and over 10uA 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/B has made the device 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/B 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.
