Overview
The L78M05T-TR-E is a three-terminal positive linear voltage regulator from the L78M series, manufactured by onsemi. It provides a fixed output voltage of 5 V with an output current capability up to 0.5 A. The device is housed in a TO-252 (DPAK) surface-mount package and includes internal protection features such as thermal overload protection, short-circuit protection, and safe area protection. Designed for local on-card regulation, it eliminates distribution problems associated with single-point regulation systems.
Feature Summary
- Provides fixed 5 V output with 0.5 A current capacity
- Includes internal thermal overload and short-circuit protection
- Utilizes TO-252 surface-mount packaging for board integration
Applications
- Local on-card voltage regulation
- General-purpose power supply circuits
- Battery-powered systems requiring stable 5 V rails
Procurement Notes
Verify the specific manufacturer designation, as the L78M series was originally developed by STMicroelectronics. Confirm that the onsemi variant maintains identical pinout and electrical characteristics to legacy ST parts if cross-referencing existing designs. Check for end-of-life notifications or alternative sourcing options given the component's long market history.
Selection Notes
Select this component when a robust, fixed 5 V source is required in a compact surface-mount form factor. Ensure the input voltage remains within the specified range to maintain regulation without excessive heat dissipation. Consider the thermal performance of the TO-252 package under maximum load conditions.
Part Context
This part belongs to the L78M family of three-terminal positive regulators, known for their reliability and simplicity. The 'T' suffix typically denotes the TO-252 package, while '-TR-E' indicates tape-and-reel packaging for automated assembly. It serves as a direct replacement for standard L78M05 devices in various industrial and consumer applications.
Replacement Considerations
Direct substitutes include the STMicroelectronics L78M05TTR and other L78M05 variants in TO-252 packages. Verify compatibility with existing PCB footprints and thermal management strategies when switching between manufacturers.
