  The LM385 series are micropower bangap voltage reference diodes.
LM385-1.2/ 2.5 are 2-terminal bandgap voltage reference diodes operate over a 15µA to 20mA current range. LM385-ADJ is 3-terminal adjustable bandgap voltage reference diode operates from 1.24V to 5.3V and over 13µA to 20mA current range. They feature exceptionally low dynamic impedance and good temperature stability. On-chip trimming is used to provide tight voltage tolerance. The LM385 bandgap reference has low noise and good long-term stability.
Careful design of the LM385 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 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 them to replace older references with tighter tolerance parts.
The LM385 is rated for operation over a 0°C to 70°C temperature range. The LM385 is available in a TO-92 and SOP-8 packages.
