LM285D-2.5 Description

LM285D-2.5 Description

The LM285D-2.5 from onsemi is a precision 2.5V shunt voltage reference designed for high-accuracy applications. Housed in an 8-SOIC package, this fixed-output reference offers a tight ±1.5% tolerance and a low temperature coefficient of 80ppm/°C (Typical), ensuring stable performance across varying environmental conditions. With a cathode current of just 30 µA, it is optimized for low-power systems. Although marked as obsolete, its low noise (120µVrms from 10Hz to 10kHz) and REACH compliance make it a reliable choice for legacy designs requiring consistent voltage regulation.

LM285D-2.5 Features

  • Precision Output: Fixed 2.5V with ±1.5% tolerance for high accuracy.
  • Low Power Consumption: Operates with a minimal 30 µA cathode current, ideal for battery-powered devices.
  • Stable Performance: 80ppm/°C temperature coefficient ensures reliability across temperature fluctuations.
  • Low Noise: 120µVrms noise over a 10Hz to 10kHz bandwidth, suitable for sensitive analog circuits.
  • Surface-Mount Design: 8-SOIC package enables compact PCB integration.
  • Obsolete but Reliable: Despite being discontinued, it remains a robust choice for legacy and low-power applications.

LM285D-2.5 Applications

  • Precision Instrumentation: Ideal for ADCs, DACs, and data acquisition systems requiring stable voltage references.
  • Portable Electronics: Low 30 µA current makes it suitable for battery-operated devices like sensors and wearables.
  • Industrial Controls: Used in process control systems where temperature stability (±80ppm/°C) is critical.
  • Legacy System Maintenance: A dependable option for repairing or upgrading older equipment without redesigns.

Conclusion of LM285D-2.5

The LM285D-2.5 is a high-precision, low-power shunt voltage reference offering excellent stability and noise performance. While obsolete, its low current draw, tight tolerance, and temperature resilience make it a strong candidate for precision analog circuits, portable devices, and industrial systems. Engineers maintaining legacy designs or seeking cost-effective references for low-power applications will find this IC a reliable solution.
