TPS78318DDCR from Texas Instruments, in a TSOT-23-5. 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 | IN | input | Input supply pin; requires 0.1-μF to 1.0-μF decoupling capacitor for stable operation. |
| 2 | GND | power_in | Ground pin; tie both ground pins to ground for proper operation. |
| 3 | EN | input | Enable pin; drive above 1.2 V to turn on regulator, below 0.4 V to shutdown reducing operating current to 18 nA. |
| 4 | GND | power_in | Ground pin; tie both ground pins to ground for proper operation. |
| 5 | OUT | output | Regulated output voltage pin; requires 1-μF or greater ceramic capacitor to ground for stable operation. |
