# RT9058-33GVL

**Richtek Tech** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L

RT9058-33GVL 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 pin for the regulator; on the SOT-23-3 (L-Type) package it is pin 1, which differs from the standard SOT-23-3 numbering where GND is pin 3. |
| 2 | VOUT | power_out | Regulator output, fixed at 3.3V for the RT9058-33; the absolute maximum rating for VOUT to GND on the RT9058-33 is −0.3V to 6V. |
| 3 | VCC | power_in | Supply voltage input with a recommended range of 3.5V to 36V; the absolute maximum rating for VCC to GND is −0.3V to 40V. |
