AP7354D-12W5-7 from Diodes Incorporated, in a SOT-25. 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 | Power input accepting 2.0V to 5.5V, with a minimum 0.1µF ceramic capacitor recommended to GND placed close to the device. |
| 2 | GND | power_in | Ground pin, which must be connected to external circuit ground as the chip ground path. |
| 3 | EN | input | Chip enable that must be driven high or low and not left floating, where high (≥1.0V) enables the output and low (≤0.4V) places the regulator in shutdown. |
| 4 | NC | unconnected | No connect pin on SOT25, shown as NC in the pin assignment diagram and not listed in the pin description table. |
| 5 | VOUT | power_out | Regulated output voltage pin (1.2V for this version) delivering up to 150mA, with an output capacitor required for stability and the active discharge feature (35Ω typical) on the D version. |
