LM385-1.2 Datasheet | National Semiconductor

description These micropower, two-terminal, band-gap voltage references operate over a 10-µA to 20-m A 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 acmodates varying current supplies with excellent regulation. The extremely low power drain of this series makes them useful for micropower circuitry. These voltage references can be used to 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 LM285-1.2 is characterized for operation from - 40°C to 85°C. The LM385-1.2 and LM385B-1.2 are characterized for operation from 0°C to 70°C.
