RS7333-1YE3L from Jiangsu RUNIC Tech, in a SOT-89-3L. 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 reference for all voltages; the GND pin must be connected to the ground plane for proper heat dissipation. |
| 2 | VIN | power_in | Regulator input accepting up to 45V, with at least a 1µF supply bypass capacitor recommended. |
| 3 | VOUT | power_out | Regulator output; the recommended output capacitor range is 1µF to 10µF. |
