Overview
The L78M10CV is a three-terminal positive linear regulator from the L78MxxA series, manufactured by STMicroelectronics. It provides a fixed output voltage of 10 V with an output current capability up to 500 mA. The device features ±2% output voltage tolerance and operates within a junction temperature range of 0°C to 125°C for the AC grade. It incorporates internal thermal overload protection, short-circuit protection, and safe area protection. The component is housed in a TO-220 package.
Feature Summary
- Provides local on-card regulation to eliminate distribution problems associated with single-point regulation.
- Includes internal current limiting, thermal shutdown, and safe area protection for robust operation.
- Delivers a fixed 10 V output with high precision and stability across varying load conditions.
Applications
- Local on-card power regulation
- General-purpose positive voltage regulation
- Battery chargers
Procurement Notes
Verify that the specific part number matches the required package type (TO-220) and temperature grade (AC). Confirm the manufacturer is STMicroelectronics to ensure compliance with the specified electrical characteristics and protection features. Check datasheet revisions for any updates to mechanical dimensions or testing conditions before finalizing procurement specifications.
Selection Notes
Select this component when a fixed 10 V output at up to 500 mA is required in a through-hole TO-220 package. Ensure the input voltage remains within the maximum ratings to prevent damage. Consider the thermal resistance values provided in the datasheet to determine if adequate heat sinking is necessary for the expected power dissipation under full load conditions.
Part Context
This device belongs to the L78MxxA series of precision 500 mA regulators available in multiple fixed output voltages. The series is designed for applications requiring reliable local regulation. The L78M10CV specifically denotes the 10 V output variant in the standard TO-220 package format.
Replacement Considerations
Compatible substitutes include other L78M10 variants from different manufacturers offering identical pinouts and electrical specifications, such as the MC78M10CDT or LM340T-10, provided they meet the same current and voltage requirements.
