XC9265A301MR-G from Torex Semicon, in a SOT-25-5. 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 | Power input pin; the datasheet gives an operating input voltage range of 2.0V to 6.0V and an absolute maximum VIN pin voltage of -0.3V to 7.0V. |
| 2 | GND | power_in | Ground reference pin; the datasheet states that all voltages are described relative to GND. |
| 3 | CE | input | Chip enable pin: H level selects operation and L level selects standby, and the pin must not be left open; the absolute maximum CE pin voltage is -0.3V to 7.0V. |
| 4 | VOUT | power_out | Regulated output voltage pin; the absolute maximum VOUT pin voltage is -0.3V to VIN + 0.3V or 7.0V, whichever is lower. |
| 5 | LX | output | Switching node pin connected to the inductor; the absolute maximum LX pin current is 1000mA and the LX pin voltage is -0.3V to VIN + 0.3V or 7.0V, whichever is lower. |
