LM285D-1.2G

Overview

The LM285D-1.2G is a micropower two-terminal bandgap voltage reference diode manufactured by onsemi. It provides a fixed output voltage of 1.25 V with an initial tolerance of 1%. The device operates within a current range of 10 µA to 20 mA and features a dynamic impedance of 1.0 Ω. It is housed in an SOIC-8 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Micropower two-terminal bandgap voltage reference design
• Low dynamic impedance for stable operation
• Surface-mount SOIC-8 packaging option

Applications

• Portable instrumentation power supplies
• Analog circuitry requiring extended battery life
• Regulator reference sources

Procurement Notes

Verify the specific suffix 'G' against the manufacturer's official ordering guide to confirm RoHS compliance status and tape-and-reel specifications. Ensure the selected package variant matches the required PCB footprint and thermal management needs for the target application environment.

Selection Notes

Select this component when a low-cost, fixed 1.25 V reference is required for space-constrained designs. The SOIC-8 package facilitates automated assembly. Consider the 1% initial tolerance and wide operating current range for applications demanding precise regulation without complex external components.

Part Context

This part belongs to the LM285/LM385 series of micropower voltage references. The 'LM' prefix indicates the industrial temperature grade (-40°C to +85°C), distinguishing it from the commercial grade LM385. The 'D' suffix denotes the SOIC-8 surface-mount package, while 'G' typically signifies lead-free/RoHS-compliant manufacturing.
