RT9058-33GX from Richtek Tech, in a SOT-89-3. 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 | VCC | power_in | Supply voltage input accepting 3.5V to 36V (absolute maximum 40V), bypassed with a 1µF or larger input capacitor placed close to VCC and GND. |
| 2 | GND | power_in | Ground. |
| 3 | VOUT | power_out | Regulator output fixed at 3.3V for the RT9058-33, up to 100mA, requiring at least 1µF effective output capacitance for stability. |
