RS6903YF5

RUNIC(润石) · Charge Pumps · SOT-23-5

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).
