RP114N331D-TR-FE from Ricoh Elec Devices, in a SOT-23-5. 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 | VDD | power_in | Input pin supplying the regulator, with an input voltage range of 1.4 V to 5.25 V. |
| 2 | GND | power_in | Ground pin, the common return for the regulator. |
| 3 | CE | input | Chip enable pin, active high ("H" Active), with an absolute maximum input voltage of 6.0 V. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output pin; the absolute maximum output voltage range is -0.3 V to VIN+0.3 V. |
