LM285Z-2.5/LFT7

Overview

The LM285Z-2.5/LFT7 is a micropower two-terminal bandgap voltage reference diode manufactured by Texas Instruments, formerly National Semiconductor. It provides a fixed output voltage of 2.5 V with an initial accuracy of ±1.5%. The device operates over a wide current range from 20 µA to 20 mA and functions within a temperature range of -40°C to +85°C. It is housed in a TO-92 plastic package with three pins.

Feature Summary

Micropower two-terminal bandgap voltage regulator design
Wide operating current range from 20 µA to 20 mA
Fixed 2.5 V output voltage with ±1.5% initial accuracy

Applications

Portable battery-powered equipment
Temperature measurement systems
Voltage reference for analog-to-digital converters

Procurement Notes

Verify the manufacturer designation as Texas Instruments (TI) despite the historical National Semiconductor branding. Confirm the specific suffix /LFT7 indicates the tape-and-reel packaging format rather than the standard through-hole variant. Ensure the component meets RoHS compliance standards as indicated by the NOPB designation in related part numbers.

Selection Notes

Select this component when a low-cost, stable voltage reference is required for circuits with limited power budgets. The wide operating current range allows flexibility in biasing resistor selection. Verify that the TO-92 package dimensions fit the available board space and that the thermal characteristics are sufficient for the intended application environment.

Part Context

This device belongs to the LM285 series of micropower voltage references. It shares functional similarities with the LM185 and LM385 series, which offer similar performance across different military, commercial, and industrial temperature grades. The Z suffix typically denotes the specific voltage binning or tolerance class within the product line.
