LD1117T-3.3 from Foshan Blue Rocket Elec, in a SOT-89. 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/ADJ | power_in | Ground pin for the fixed-output LD1117T-3.3; on the adjustable (LD1117T-Adj) variant this pin is the ADJ pin, with adjustment pin current Iadj of 60 uA typical and 120 uA maximum. |
| 2 | VOUT | power_out | Regulated output pin, rated for output current up to 800mA with internal current and thermal limiting. |
| 3 | VIN | power_in | Input supply pin; the absolute maximum input voltage is 15 V and the LD1117T-3.3 operating input range is 4.75 V to 15 V at Io=0mA. |
