AP1501S-12RG from HANSCHIP semiconductor, in a TO-263-5. 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 | Supply input pin requiring a DC supply of 4.5 V to 40 V, with a large-value capacitor connected between the supply pin and ground to suppress supply noise. |
| 2 | OUTPUT | output | Power switch output pin, a switching node that supplies the output load, with a stated saturation voltage of 1.5 V typical at 3 A. |
| 3 | GND | power_in | Ground pin that must be routed outside the Schottky diode to output capacitor ground path so that switching current spikes do not add noise to the circuit. |
| 4 | FEEDBACK | bidirectional | Voltage feedback pin that senses the output voltage through an external resistor divider, with a feedback threshold of 1.23 V. |
| 5 | ON_OFF | input | Enable/shutdown pin where a low level turns the chip on and a high level turns it off, with thresholds of 0.8 V (on) and 1.4 V (off) and defaulting to low when floating. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
