LM385D-1.2R2

Overview

The LM385D-1.2R2 is a micropower two-terminal bandgap voltage reference diode manufactured by onsemi. It provides a fixed nominal output voltage of 1.235 V. The device is designed to operate over a wide current range from 10 µA to 20 mA, featuring low dynamic impedance and low noise for stable operation. It is housed in an SOIC-8 surface-mount package.

Feature Summary

Micropower two-terminal bandgap voltage regulator diode
Fixed 1.235 V output voltage
Wide operating current range from 10 µA to 20 mA
Low dynamic impedance and low noise characteristics

Applications

Portable instrumentation
Battery-powered regulators
Analog circuitry requiring extended battery life

Procurement Notes

Verify the specific suffix 'R2' against the official onsemi datasheet to confirm tape-and-reel packaging quantities and exact tolerance grades. Ensure the SOIC-8 package matches the design footprint. Confirm RoHS compliance status as manufacturing processes may vary.

Selection Notes

Select this component when a fixed 1.235 V reference is required in a surface-mount application. It is suitable for designs needing low quiescent current operation within the 10 µA to 20 mA range. Compare with through-hole TO-92 variants if space constraints allow for alternative packaging.

Part Context

This part belongs to the LM385 series of micropower voltage references. Unlike the LM285 which operates over an industrial temperature range (-40°C to +85°C), the LM385 is rated for commercial temperatures (0°C to +70°C). The 'D' suffix indicates the SOIC-8 surface-mount package.
