Overview
The L7815ACD2T-TR is a fixed positive linear voltage regulator from the STMicroelectronics L78xx series. It provides a fixed 15V output with a maximum output current of 1.5A. The device supports a maximum input voltage of 35V and operates within a temperature range of 0°C to +125°C. Key electrical parameters include a typical static current of 4.4mA. It is housed in a surface-mount D2PAK package.
Feature Summary
- Integrates internal current limiting, thermal shutdown, and safe area protection for robust operation.
- Provides local on-card regulation to eliminate distribution problems associated with single-point regulation.
- Available in surface-mount D2PAK packaging for efficient board space utilization.
Applications
- Local on-card voltage regulation
- General-purpose positive power supplies
- Battery chargers
Procurement Notes
Verify the specific suffix 'CD2T' confirms the D2PAK surface-mount package and tape-and-reel delivery format. Confirm the 'A' grade designation matches required performance tolerances. Ensure the 15V fixed output aligns with system requirements. Check for RoHS compliance status if mandated by project specifications.
Selection Notes
Select this component when a fixed 15V output is required in a compact surface-mount form factor. The D2PAK package offers improved thermal dissipation compared to smaller SOT packages. Consider the 35V maximum input voltage limit and ensure adequate heat sinking is provided to support the 1.5A output capability under expected load conditions.
Part Context
This part belongs to the L78xx family of three-terminal positive regulators. The series includes various fixed output voltages and multiple package options such as TO-220, TO-220FP, and DPAK. The L7815ACD2T-TR specifically utilizes the D2PAK surface-mount variant for modern PCB assembly needs.
Replacement Considerations
L7815ABD2T-TR: Similar L7815 variant in D2PAK package; verify specific electrical parameter differences between 'A' and 'B' grades before substitution.
