description

These micropower two-terminal band-gap voltage references operate over a 20-µA to 20-mA current range and

feature exceptionally low dynamic impedance and good temperature stability. On-chip trimming provides tight

voltage tolerance. The band-gap reference for these devices has low noise and long-term stability.

The design makes these devices exceptionally tolerant of capacitive loading and thus, easier to use in most

reference applications. The wide dynamic operating temperature range accommodates varying current

supplies with excellent regulation.

The extremely low power drain of this series makes them useful for micropower circuitry. These voltage

references can make portable meters, regulators, or general-purpose analog circuitry with battery life

approaching shelf life. The wide operating current range allows them to replace older references with

tighter-tolerance parts.

The LM285-2.5 is characterized for operation from –40°C to 85°C. The LM385-2.5 and LM385B-2.5 are

characterized for operation from 0°C to 70°C.
