AP7343-33W5-7 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 pin; the datasheet gives a wide input range of 1.7V to 5.25V (absolute maximum 6.0V). |
| 2 | GND | power_in | Ground pin; the regulator ground should be connected to the external circuit ground to reduce voltage drop from trace impedance. |
| 3 | EN | input | Enable input that must be driven high or low and must not float; high (minimum 1.3V, maximum 5.25V) turns the regulator on and low (maximum 0.5V) puts it into shutdown. |
| 4 | NC | unconnected | No connection pin, not used internally. |
| 5 | VOUT | power_out | Regulated power output pin; the fixed output is 3.3V for this -33 variant and output current is guaranteed up to 300mA. |
