Overview
The L78M10CDT is a precision 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 is housed in a surface-mount DPAK package and features internal thermal overload protection, short-circuit protection, and output safe-area protection. It operates within a DC input voltage range of 12.5 V to 30 V for optimal regulation. The component exhibits a typical quiescent current of 6 mA and maintains a line regulation of 30 mV under specified conditions.
Feature Summary
- Integrated thermal overload protection that shuts down the circuit during excessive power overload conditions
- Internal short-circuit protection limits maximum output current to prevent damage
- Output transistor safe-area compensation reduces output current as voltage across the pass transistor increases
Applications
- Local on-card voltage regulation
- Current regulator circuits
- Adjustable output regulator configurations
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and environmental compliance grade. Ensure the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity. Confirm that the received parts match the exact part number specifications regarding electrical characteristics and physical dimensions before integration into production.
Selection Notes
Select this component when a fixed 10 V output is required with a maximum load current of 500 mA. The DPAK package is suitable for surface-mount applications where space efficiency is prioritized. Consider the thermal resistance characteristics of the package for heat dissipation requirements. Verify that the input voltage remains within the specified operational range to ensure stable regulation and proper function of internal protection mechanisms.
Part Context
This device belongs to the L78MxxA series of precision regulators available in TO-220 and DPAK packages. The series offers various fixed output voltages including 5, 6, 8, 9, 10, 12, 15, and 24 V. These regulators are designed to eliminate distribution problems associated with single-point regulation by providing local control on the circuit board.
Replacement Considerations
Compatible substitutes include other variants within the L78MxxA series such as L78M12ABDT-TR or L78M15ABDT-TR, provided the output voltage requirement matches the application needs. Cross-referencing pinouts and thermal characteristics is essential when substituting devices.
