LM385PWR-2-5

Overview

The LM385PWR-2-5 is a fixed shunt voltage reference integrated circuit manufactured by Texas Instruments. It provides a nominal output voltage of 2.5V with an initial accuracy tolerance of ±3%. The device operates within a temperature range of 0°C to 70°C and features a standard temperature coefficient of 20ppm/°C. It supports a maximum cathode current of 20mA and requires a minimum operating current of 20µA. The component is housed in an 8-TSSOP surface-mount package, measuring 4.40mm in width.

Feature Summary

Micro-power shunt voltage reference design suitable for low-current applications
Fixed 2.5V output with high long-term stability and low noise characteristics
Capacitive load tolerant topology simplifies integration in reference circuits

Applications

Portable instrumentation requiring stable reference voltages
Battery-powered systems where power efficiency is critical
Current loop instruments and panel meters

Procurement Notes

Verify the specific suffix 'PWR' confirms the 8-TSSOP package and 2.5V fixed output variant. Confirm RoHS compliance status as manufacturing revisions may affect regulatory markings. Ensure the source document explicitly lists this part number to avoid confusion with similar LM385 series components or alternative packages like SOIC.

Selection Notes

Select this component when a fixed 2.5V reference is required in a compact surface-mount footprint. The 20µA minimum current requirement must be accommodated in the biasing circuit design. Verify that the 0°C to 70°C operating range meets the environmental specifications of the target application.

Part Context

This component belongs to the LMx85 family of micro-power, dual-terminal zener-like voltage references. These devices utilize bandgap technology to provide precise voltage regulation across a wide dynamic current range from 20µA to 20mA. The family is characterized by low dynamic impedance and excellent temperature stability.
