TLV1117-33IDCYR from Texas Instruments, in a SOT-223-4. 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 | Ground reference providing current return path for input and output circuits; rated for 800mA output current maximum. |
| 2 | VOUT | power_out | Regulated 3.3V output capable of 0-800mA load current; requires output capacitor with ESR 2-500mΩ and 10µF minimum capacitance for stability. |
| 3 | VIN | power_in | Positive supply input accepting 4.7-15V for TLV1117-33; requires minimum 0.4V dropout voltage at 100mA to 1.2V at 800mA for linear regulation. |
| 4 | VOUT | power_out | Regulated 3.3V output capable of 0-800mA load current; typically paralleled with Pin 2 for improved current distribution and reduced trace impedance. |
