L78M06CV

Overview

The L78M06CV is a three-terminal positive linear voltage regulator from the STMicroelectronics L78M series, designed for fixed output applications. It provides a nominal 6 V output with a maximum continuous current capability of 500 mA. The device operates within an input voltage range up to 35 V and supports junction temperatures up to 150 °C. Packaged in a TO-220 through-hole format, it integrates internal protection mechanisms including thermal overload shutdown and short-circuit limiting.

Feature Summary

• Integrated thermal overload protection prevents damage during excessive heat conditions
• Built-in short-circuit protection ensures robust operation under fault conditions
• Fixed 6 V output eliminates distribution problems associated with single-point regulation

Applications

• Local on-card voltage regulation
• General-purpose power supply circuits
• Battery chargers

Procurement Notes

Verify the specific suffix 'M' confirms the 500 mA current rating distinct from standard L78 variants. Confirm the 'CV' designation aligns with the required TO-220 package style. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number against official distributor catalogs to confirm availability status.

Selection Notes

Select this component when a fixed 6 V rail is required with moderate current demands up to 500 mA. It serves as a direct replacement for other manufacturers' equivalent 6 V regulators in the L78M family. Consider the thermal dissipation capabilities of the TO-220 package relative to the expected load current and ambient temperature conditions.

Part Context

This part belongs to the L78Mxx series of three-terminal positive regulators, offering lower current capacity than the standard L78xx line. It shares the same pinout and functional architecture but is optimized for compact designs requiring up to 500 mA. The series is widely used in consumer electronics and industrial control systems for stable voltage derivation.

Replacement Considerations

Equivalent parts include LM78M06, MC78M06, and UA78M06. Verify pin compatibility and thermal characteristics before substitution.
