RS6903YF5 from RUNIC(润石), 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 | OUT | power_out | Power output with VOUT = -VIN; bypass OUT to GND with the output filter capacitor COUT (3.3 µF in Table 1, 3.3 µF to 47 µF allowed in Section 8.3). |
| 2 | IN | power_in | Supply input for 1.5 V to 5.5 V; bypass IN to GND with a capacitor of the same value as the flying capacitor. |
| 3 | CFLY- | passive | Negative terminal of the flying capacitor CFLY (3.3 µF). |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | CFLY+ | passive | Positive terminal of the flying capacitor CFLY (3.3 µF). |
