TPS78342DDCR 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 | power_in | Input pin; place a small 0.1-μF capacitor from this pin to ground for stable operation, with a typical input capacitor of 1.0 μF, and tie the 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 it above 1.2 V to turn on the regulator and 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 | power_out | Regulated output voltage pin; connect a small (1-μF or greater) ceramic capacitor from this pin to ground for stable operation. |
