RT9058-50GVL from Richtek Tech, in a SOT-23-3L. 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 pin for the regulator, and the GND pin to be placed close to the output capacitor return. |
| 2 | VOUT | power_out | Regulated output of the RT9058; for the RT9058-50 (5.0V) the VOUT to GND absolute maximum is -0.3V to 6V and the output capacitor needs at least 1µF effective capacitance with a minimum 1mΩ ESR. |
| 3 | VCC | power_in | Supply voltage input with a recommended range of 3.5V to 36V (absolute maximum VCC to GND is -0.3V to 40V), to be decoupled with at least 1µF close to the pin. |
