AH1117CLTR33 from BL Shanghai Belling, in a SOT-223-3. 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 | Vss/ADJ | power_in | Ground pin on fixed-voltage versions (adjustable pin on the ADJ version, which has a 1.25V reference and 55uA typical adjust current). |
| 2 | Vout | power_out | Regulated output voltage (3.3V ±2% for the AH1117CLTR33), up to 1A maximum output current. |
| 3 | Vin | power_in | Supply voltage input, 15V absolute maximum and 12V maximum recommended. |
