RP170N331D-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; recommended input voltage range is 2.6V to 10V (absolute maximum 12V), with a 1.0µF or larger capacitor placed close between VDD and GND. |
| 2 | GND | power_in | Ground pin. |
| 3 | CE | input | Chip enable pin, active high: VCEH min 1.7V, VCEL max 0.8V, absolute maximum 12V, with a CE pull-down current of typ. 0.30µA. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output pin delivering up to 300mA, needing an output capacitor of 1.0µF or more for stable operation. |
