LM120H-12/NOPB

Overview

The LM120H-12/NOPB is a three-terminal negative voltage regulator from the Texas Instruments LM120 series. It provides a fixed output of -12 V with a maximum load current capability of 1.5 A. The device operates within an input voltage range of -7 V to -30 V and maintains regulation across a junction temperature range of 0°C to +150°C. Packaged in a TO-220-3 through-hole case, it features internal protection mechanisms including thermal shutdown and current limiting.

Feature Summary

• Fixed negative voltage regulation
• Integrated thermal and current protection

Applications

• Negative power supply rails for analog circuits
• Industrial control systems requiring stable negative bias
• General-purpose linear regulation applications

Procurement Notes

Verify the specific suffix 'H' against the official datasheet to confirm the exact temperature grade and package variant. Ensure the ordering part number matches the required lead time and availability status directly from Texas Instruments or authorized distributors. Confirm RoHS compliance details as specified in the latest documentation.

Selection Notes

Select this component when a fixed -12 V output is required with up to 1.5 A load capacity. Consider the TO-220-3 package for through-hole mounting and adequate heat dissipation. Verify that the input voltage remains within the specified -7 V to -30 V range to ensure proper operation and protection activation.

Part Context

This part belongs to the LM120/LM320-N series of three-terminal negative regulators manufactured by Texas Instruments. These devices are designed for general-purpose linear regulation tasks where a stable negative voltage rail is necessary. The series is known for robust performance in industrial and commercial environments.

Replacement Considerations

Compatible substitutes include the LM320N-12/NOPB and LM120N-12/NOPB. Verify pinout compatibility and thermal characteristics before substitution.
