LM385BZ-1.2/NOPB

Overview

The LM385BZ-1.2/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, featuring a nominal output voltage of 1.235 V with an initial accuracy of ±2.0%. Housed in a TO-92 three-pin through-hole package, it operates within a temperature range of 0°C to +70°C and exhibits a maximum voltage temperature coefficient of 150 ppm/°C. The device supports a maximum shunt current of 20 mA and utilizes bipolar technology for stable performance in commercial applications.

Feature Summary

Provides a fixed 1.235 V reference output suitable for precision analog circuits
Operates over a wide current range from microamps to 20 mA
Utilizes a robust TO-92 through-hole package for reliable mounting

Applications

Portable battery-powered instrumentation requiring low quiescent current
Data acquisition systems utilizing analog-to-digital converters
Temperature sensing circuits requiring stable reference voltages

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance when sourcing. Confirm the package type matches the required TO-92 form factor for the target PCB layout. Ensure the operating environment remains within the specified commercial temperature limits to maintain the stated accuracy specifications during operation.

Selection Notes

Select this component when a fixed 1.2 V reference is needed in a through-hole configuration. It serves as a direct replacement for older LM385 variants without the NOPB suffix. Consider the ±2.0% tolerance if higher precision is not critical, or explore the B-grade variants for tighter tolerances if budget allows.

Part Context

This part belongs to the LM385 family of micropower voltage references designed for cost-sensitive applications. It offers a stable reference voltage in a compact TO-92 package, making it ideal for space-constrained designs that do not require surface-mount technology. The device is widely used in general-purpose electronic equipment.

Replacement Considerations

LM385BZ-1.2 is the predecessor to the LM385BZ-1.2/NOPB variant. Verify compatibility with existing circuit designs when transitioning between these versions.
