AP1507-D5-13 from Diodes Incorporated, in a TO-252-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Operating voltage input (4.5V to 22V) for the regulator, requiring a suitable input bypass capacitor to minimize voltage transients and supply switching currents. |
| 2 | Output | output | Internal switching output that swings between (VIN - VSAT) and approximately -0.5V with duty cycle of about VOUT/VIN, and its PCB copper area should be kept minimal. |
| 3 | GND | power_in | Circuit ground. |
| 4 | FB | input | Output voltage feedback control pin that senses the regulated output voltage to close the loop (VFB = 1.23V typical for the adjustable version, -0.3 to +18V). |
| 5 | SD | input | ON/OFF shutdown input where below about 1.3V turns the regulator on and above 1.3V (up to 18V maximum) shuts it down, and it can be wired to ground if unused. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
