used to provide tight voltage tolerance. Since the

LM185 band-gap reference uses only transistors and

resistors, low noise and good long-term stability

result.

Careful design of the LM185 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 LM185 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.
