LM285Z-2.5

Overview

The LM285Z-2.5/NOPB is a micropower voltage reference diode manufactured by Texas Instruments, formerly National Semiconductor. It operates within a temperature range of -40°C to +85°C and provides a fixed output voltage of 2.5 V. The device features an initial accuracy of 1.5% and a temperature coefficient of 150 ppm/°C. It supports a maximum shunt current of 20 mA and is housed in a TO-92-3 through-hole package.

Feature Summary

Micropower two-terminal bandgap voltage regulator diode
Stable operation over time and temperature
Low dynamic impedance and low noise characteristics

Applications

Portable instrumentation
Regulators
Analog circuitry requiring extended battery life

Procurement Notes

Verify the manufacturer designation carefully, as the component was originally produced by National Semiconductor before its acquisition by Texas Instruments. Confirm that the suffix /NOPB indicates lead-free compliance and RoHS adherence. Ensure the specific ordering part number matches the required package style and tolerance specifications for your design requirements.

Selection Notes

Select this component when a stable 2.5 V reference is needed in low-power applications. Consider the 1.5% initial accuracy and 150 ppm/°C temperature coefficient against your circuit's precision requirements. The TO-92 package suits through-hole designs, while other series members offer surface-mount options if board space is constrained.

Part Context

This device belongs to the LM285/LM385 series of micropower voltage references. These devices are designed for wide current ranges and feature tight voltage tolerances achieved through on-chip trimming. The series is widely used in applications requiring excellent regulation across varying supply conditions.
