TPS78218DDCR 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 pin. For stable operation, place a small, 0.1-µF capacitor from this pin to ground; typical input capacitor = 1.0 µF. Tie back both input and output capacitor grounds to the IC ground, with no significant impedance between them. |
| 2 | GND | power_in | Ground pin. Tie all ground pins to ground for proper operation. |
| 3 | EN | input | Enable pin. Drive this pin over 1.2 V to turn on the regulator. Drive this pin below 0.4 V to put the regulator into shutdown mode, reducing operating current to 18 nA typical. |
| 4 | GND | power_in | Ground pin. Tie all ground pins to ground for proper operation. |
| 5 | OUT | output | Regulated output voltage pin. A small (1-μF) ceramic capacitor is needed from this pin to ground to assure stability. |
