- Features built-in safe operating area protection
Applications
- General purpose linear regulators
- Local on-card regulation
- Power supply circuits
Procurement Notes
Verify that the component matches the specified TO-252 (D2PAK) package outline and pin configuration before integration. Confirm the marking code corresponds to the L7808CD2T designation to ensure correct voltage rating. Check datasheet specifications for absolute maximum ratings regarding input voltage differential and junction temperature limits during design validation.
Selection Notes
Select this component when a fixed +8V DC output is required from a higher unregulated source. Ensure the input voltage remains within the recommended range to maintain proper line regulation and dropout performance. Consider thermal management requirements based on the expected power dissipation and ambient operating conditions for the specific application environment.
Part Context
This part is a member of the widely adopted 78xx family of linear regulators, known for their simplicity and robustness. The 'L78' prefix typically denotes the series, while '08' indicates the 8-volt output variant. The 'CD2T' suffix specifies the surface-mount D2PAK package type, distinguishing it from through-hole alternatives like the TO-220 version.
Replacement Considerations
Compatible substitutes include MC7808CD2T from ON Semiconductor/NXP and KA78T08 equivalents. Verify pinout compatibility and thermal characteristics when cross-referencing with other manufacturers' offerings to ensure direct replacement functionality.
