LM385-25/LM385B-25

Micropower Voltage Reference

FEATURES

Operating Current from 20μA to 20mA.

Low Temperature Coefficient.

1% and 2% Initial Tolerance.

Low Dynamic Impedance.

DESCRIPTION

The LM385-25 is a micropower 2-terminal

bandgap voltage reference, which can operate in

a 20μA 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

LM385-25 bandgap reference uses only

transistors and resistors, low noise and good

long-term stability result.

Careful design of the LM385-25 has made the

device exceptionally tolerant of capacitive

loading, making it easy to use in almost any

reference application. The wide dynamic

operating range allows for its use with widely

varying supplies with excellent regulation.

The extremely low power drain of the LM385-25

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.

APPLICATIONS
