L78S75CV-DG

Overview

The L78S75CV-DG is a positive linear voltage regulator from the STMicroelectronics L78S series, designed for local card-level regulation. It provides a fixed output voltage of 7.5 V with a maximum output current capability of 2 A. The device features internal safety protections including thermal shutdown and current limiting to ensure reliability under fault conditions. It is housed in a TO-220-3 package suitable for through-hole mounting.

Feature Summary

• Fixed 7.5 V output voltage regulation
• High current delivery up to 2 A
• Integrated thermal overload protection
• Internal short-circuit current limiting

Applications

• Local on-board voltage regulation
• Power supply conditioning circuits
• Embedded system power management

Procurement Notes

Verify the specific suffix 'DG' against the manufacturer's official documentation to confirm environmental compliance or packaging variations. Ensure the component matches the required pinout and thermal characteristics for the target application design.

Selection Notes

Select this component when a stable 7.5 V rail is required with up to 2 A load capacity. Consider the thermal dissipation requirements inherent to linear regulation at higher input-output differentials and verify compatibility with the TO-220-3 footprint.

Part Context

This part belongs to the L78S family of 2 A positive voltage regulators. It shares functional similarities with other L78 series devices but offers higher current handling than the standard 1.5 A variants. The L78S series is widely used in industrial and consumer electronics for robust linear regulation.

Replacement Considerations

Compatible substitutes include other L78S series regulators with equivalent voltage ratings, such as the L78S05CV or L78S12CV, provided the output voltage matches the system requirement. Cross-reference pinouts and thermal performance before substitution.
