LM385LP-1-2

Overview

The LM385LP-1-2 is a micropower shunt voltage reference from Texas Instruments, providing a fixed nominal output of 1.235 V. It features an initial accuracy of ±1% and a temperature coefficient of ±20 ppm/°C. The device operates within a current range of 15 µA to 20 mA and supports a maximum load current of 20 mA. It is designed for commercial applications with an operating temperature range of 0°C to +70°C. The component utilizes a TO-226AA (TO-92) three-pin through-hole package.

Feature Summary

Provides a stable 1.235 V reference voltage suitable for precision analog circuits
Operates over a wide cathode current range from 15 µA to 20 mA
Maintains low temperature drift for consistent performance across commercial temperatures

Applications

Portable battery-powered instrumentation
Data acquisition systems
Microprocessor supervisory circuits

Procurement Notes

Verify the specific suffix 'LP' confirms the TO-226AA through-hole package variant. Confirm RoHS compliance status as manufacturing processes may evolve. Check for active production status or obsolescence notices from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this component when a fixed 1.235 V reference is required in a through-hole design. Ensure the application current remains above 15 µA for regulation. Consider the ±1% initial tolerance if tighter accuracy is needed, which may require alternative B-grade variants.

Part Context

This part belongs to the LM385 family of micropower shunt voltage references. It serves as a low-cost, high-precision alternative to Zener diodes. The LM385 series is widely used in general-purpose analog applications requiring a stable voltage baseline.
