TPS79918QDDCRQ1 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 supply voltage from 2.7V to 6.5V. |
| 2 | GND | power_in | Ground; the pad must be tied to GND. |
| 3 | EN | input | Enable input; driving high enables the regulator, driving low enters shutdown mode. |
| 4 | NR | passive | Noise reduction pin for fixed-voltage versions; connect external capacitor to bypass internal bandgap noise and reduce output noise. |
| 5 | OUT | power_out | Regulated output; requires a capacitor (≥2μF ceramic) connected from this pin to ground to ensure stability. |
