RS3007-5.0AYF3

Jiangsu RUNIC Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

RS3007-5.0AYF3 from Jiangsu RUNIC Tech, in a SOT-23-3. 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 GND power_in Ground pin; the datasheet says the GND pin must be connected to the ground plane for proper heat dissipation.
2 VOUT power_out Regulator output; recommended output capacitor range is 1µF to 10µF.
3 VIN power_in Regulator input, up to 45V; at least a 1µF supply bypass capacitor is recommended.
