The LD1117DT33TR is supplied in a DPAK (TO-252) package. This package type is commonly used for surface-mounted electronic components, allowing for efficient heat dissipation and space-saving on printed circuit boards.

The LD1117DT33TR is a low-dropout linear voltage regulator. It typically comes in a DPAK (TO-252) package, which is a 3-pin configuration plus a tab for heat dissipation. The pin count and functions are as follows:
1. Pin 1 (ADJ/GND/NC): This can serve as an adjustment pin for the adjustable version, a ground pin for the fixed version, or not connected (NC) depending on the specific model.
2. Pin 2 (VOUT): This is the output pin where the regulated voltage is provided.
3. Pin 3 (VIN): This is the input pin where the unregulated input voltage is applied.
The tab is often connected to ground and helps in heat dissipation. The specific version, LD1117DT33TR, is a fixed 3.3V output version, thus the first pin is usually a ground pin. Always refer to the manufacturer's datasheet for precise information regarding pin configuration and connections.
