RT9013-33GB from Richtek Tech, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Enable input, active high (TTL-logic controlled). V_IH ≥ 1.6V enables the regulator; V_IL ≤ 0.6V places the device in shutdown mode (I_SHDN typ 0.7µA). Absolute-max 6V; do not float - tie through a 100k pull-down if unused. |
| 2 | GND | power_in | Common ground reference for the regulator. Provides the return path for input, output, and internal reference currents. |
| 3 | VIN | power_in | Supply input. Operating range 2.2V to 5.5V, absolute-max 6V. Bypass with a 1µF ceramic (X7R) capacitor close to the pin for stability and transient response. |
| 4 | NC | unconnected | No internal connection. May be left floating or tied to GND for best PCB layout practice. |
| 5 | VOUT | power_out | Regulated output, fixed 3.3V (±2% accuracy at 10mA). Sources up to 500mA with 250mV typical dropout at full load. Requires only a 1µF ceramic (X7R) output capacitor for stability; current limit typ 0.5-0.6A. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 567 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
