**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220-3

TLV1117IKCS from Texas Instruments, in a TO-220-3. 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 | ADJ/GND | bidirectional | Adjust pin on the adjustable version (ADJ, which this TLV1117IKCS is) and ground pin on fixed-output versions; the datasheet lists its type as I/O and gives no other limit for this pin. |
| 2 | VOUT | output | Regulator output pin, rated for up to 800 mA output current; the adjustable version produces an output from 1.25 V to 13.8 V. |
| 3 | VIN | power_in | Regulator input pin; the recommended input range for the TLV1117 is 2.7 V to 15 V, and the absolute maximum continuous input voltage is 16 V. |
