LM120H-15/NOPB

Overview

The LM120H-15/NOPB is a linear voltage regulator from Texas Instruments designed for negative voltage applications. It provides a fixed output of -15 V with a maximum output current of 1.5 A. The device operates within an input voltage range of -30 V to -7 V and features a typical power supply rejection ratio (PSRR) of 70 dB. It includes line regulation of 100 mV and load regulation of 200 mV. The component supports through-hole mounting in a TO-220-3 package and functions reliably across an operating temperature range of 0°C to +125°C.

Feature Summary

Provides stable negative voltage regulation with fixed output capability
Integrates thermal overload protection to prevent junction temperature exceedance
Features internal current limiting to protect against short-circuit faults

Applications

Negative power supply rails in electronic circuits
Industrial control systems requiring robust voltage regulation
Test and measurement equipment power management

Procurement Notes

Verify the specific suffix 'H' indicates the military-grade extended temperature variant (-55°C to +150°C) rather than the commercial grade, as datasheets may vary. Confirm the package type matches the required TO-220 or TO-39 footprint. Ensure the negative polarity requirement aligns with system design before procurement.

Selection Notes

Select this component when a fixed negative voltage rail is required with high current capacity. Consider the thermal dissipation capabilities of the TO-220 package for heat management. Verify that the input voltage differential allows for sufficient dropout voltage under maximum load conditions.

Part Context

This part belongs to the LM79 series of three-terminal negative linear regulators. It serves as a standard solution for generating negative voltages in mixed-signal systems. The NOPB suffix denotes a lead-free and environmentally compliant manufacturing process.
