LF120CV

Overview

The LF120CV is a fixed positive linear voltage regulator manufactured by STMicroelectronics, delivering a precise 12V output with a maximum current capacity of 500mA. It operates within an input voltage range up to 16V and features a very low drop voltage characteristic. The device is housed in a TO-220AB package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

Provides a stable fixed 12V DC output for power supply applications
Supports continuous load currents up to 500mA
Features very low drop voltage operation for improved efficiency
Includes thermal protection mechanisms for safe operation

Applications

General purpose linear power supplies
Battery-powered equipment requiring stable 12V rails
Industrial control systems
Embedded electronics power regulation

Procurement Notes

Verify the exact ordering suffix matches LF120CV to ensure correct package type (TO-220AB) and electrical specifications. Confirm RoHS compliance status if required for specific manufacturing standards. Check datasheet revisions for any updates to thermal resistance or pinout configurations before finalizing procurement.

Selection Notes

Select this component when a fixed 12V output is required with moderate current demands up to 500mA. Ensure the input voltage does not exceed 16V to prevent damage. Consider the thermal dissipation requirements given the linear regulation topology and the TO-220 package's thermal characteristics under load conditions.

Part Context

This part belongs to STMicroelectronics' family of very low drop voltage regulators with inhibit functionality. It is designed for applications requiring simple, reliable linear regulation without the complexity of switching converters. The TO-220 package facilitates easy mounting on heat sinks for higher power dissipation scenarios.

Replacement Considerations

Consult official STMicroelectronics documentation for direct cross-references. Verify pin compatibility and electrical parameters such as dropout voltage and output current capability against alternative LDO regulators from other manufacturers before substitution.
