H7533-1 from Shanghai Siproin Microelectronics, in a SOT-89-3. 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 | GND | power_in | Device ground / common return for both input and output. Reference for the internal bandgap and feedback network. |
| 2 | VIN | power_in | Unregulated supply input. Absolute max 18V; recommended operating range up to 15V (H7533-1 line-regulation window 4.5V ≤ VIN ≤ 16V). Bypass close to the pin with a small ceramic capacitor. |
| 3 | VOUT | power_out | Regulated 3.3V output (3.234V - 3.366V, ±2%). Sources up to 150mA typical. Requires an output capacitor for stability; low-ESR ceramic recommended. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 275 faces against 42 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.
