LP3220AB5F from LOWPOWER, 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 pin. Active high (V_EN(H) >= 1.4V; V_EN(L) <= 0.4V). In shutdown, all functions are disabled drawing <1uA supply current. |
| 2 | GND | power_in | Ground reference for the converter. |
| 3 | LX | output | Switch Mode Connection to Inductor. This pin connects to the drains of the internal main and synchronous power MOSFET switches. Connect a 2.2uH inductor to the output filter. |
| 4 | VIN | power_in | Power supply input pin (2.2V to 5.5V). Must be closely decoupled to GND with a 10uF or greater ceramic capacitor. |
| 5 | FB/Vout | input | Feedback input. For the adjustable LP3220AB5F variant, connect a resistor divider from Vout to set the output voltage against the 0.6V internal reference (V_FB typ 0.6V, 0.588-0.612V). For fixed-output variants this pin ties directly to Vout. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 496 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.
