TLV1117-18CDCYR from Texas Instruments, in a SOT-223-4. 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 | ADJ/GND | power_in | Ground pin for fixed output version, serves as reference for the feedback network. |
| 2 | VOUT | power_out | Regulated output voltage pin, 1.8V nominal, with 800 mA maximum output current. |
| 3 | VIN | power_in | Input voltage pin, rated for 3.2 V to 15 V supply range. |
| 4 | VOUT | power_out | Output thermal pad providing the 1.8 V regulated voltage, internally connected to pin 2 output. |
