AP1084KG-13 from Diodes Incorporated, in a TO-263. 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 | Adj (GND) | input | Adjustable pin: a resistor divider from this pin to VOUT and ground sets the output voltage, and this pin is ground only in fixed-mode versions. |
| 2 | VOUT | power_out | Regulator output, which requires a minimum of 10uF capacitor with 0.15Ω ≤ ESR ≤ 20Ω connected from this pin to ground for stability; the tab is also VOUT. |
| 3 | VIN | power_in | Input pin, which must always be 1.4V (1.3V) higher than VOUT for the device to regulate properly, with a large storage capacitor typically connected to ground to prevent sag during load transients. |
