Overview
The L78S12CV-DG is a positive voltage regulator IC from the STMicroelectronics L78S series, designed for fixed-output applications. It provides a stable 12V output with a maximum load current of 2A. The device features internal protections including thermal overload shutdown and short-circuit limiting to ensure reliability under fault conditions. It utilizes a TO-220 package suitable for through-hole mounting, supporting an operating temperature range from 0°C to +125°C.
Feature Summary
- Fixed 12V positive output regulation
- Internal thermal overload protection
- Short-circuit current limiting
Applications
- General-purpose linear power supplies
- Local on-card regulation circuits
- Embedded system power management
Procurement Notes
Verify the specific suffix 'DG' against the manufacturer's official documentation to confirm RoHS compliance status and exact pinout configuration. Ensure the selected component matches the required 2A current rating and TO-220 package dimensions for your PCB layout. Cross-reference the datasheet revision date to guarantee compatibility with your design specifications.
Selection Notes
Select this component when a fixed 12V output at up to 2A is required in a through-hole format. Compare against the standard L7812 series if lower current (1.5A) is sufficient, as the L78S variant offers higher current capability. Consider thermal dissipation requirements due to the linear regulation topology and potential heat generation under high load or input-output differential.
Part Context
This part belongs to the L78S family of 2A positive voltage regulators by STMicroelectronics. It serves as a robust solution for applications needing higher current than the standard L78xx series. The device eliminates the need for external feedback components, offering a simple three-terminal interface for easy integration into power supply designs.
Replacement Considerations
The L78S12CV is functionally compatible with other 2A positive 12V regulators in TO-220 packages. Verify pinout alignment before substituting with equivalents from other manufacturers. Standard L7812 devices are not direct replacements due to their lower 1.5A current rating.
