LM385LPR-1-2

Overview

The LM385LPR-1-2 is a micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 1.235 V with an initial accuracy tolerance of ±2%. The device operates within a temperature range of 0°C to +70°C and features a typical temperature coefficient of 20 ppm/°C. Maximum cathode current is 15 µA, while the maximum output current capability reaches 20 mA. Noise performance is specified at 60 µVrms over the 10 Hz to 10 kHz frequency band. The component is housed in a TO-92-3 (TO-226AA) through-hole package.

Feature Summary

Provides a stable 1.235 V reference voltage suitable for precision applications
Operates with low quiescent current for energy-efficient designs
Features high stability with low temperature drift characteristics
Designed as a shunt reference requiring minimal external components

Applications

Portable battery-powered instrumentation systems
Microprocessor supply monitoring circuits
Data acquisition system reference sources
Temperature measurement sensor interfaces

Procurement Notes

Verify the specific suffix LPR indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the TO-92-3 package variant matches the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a precise 1.235 V reference with tight tolerance. Consider the ±2% accuracy and 20 ppm/°C drift for calibration needs. Evaluate the 20 mA current limit against load requirements. Verify the through-hole mounting style aligns with assembly processes.

Part Context

This part belongs to the LM385 family of micropower voltage references from Texas Instruments. It serves as a compact solution for establishing accurate voltage levels in analog signal chains. The series offers various packages and voltage options to support diverse electronic design constraints.
