TPS79930DDCT 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 pin; VIN must be between 2.7 V and 6.5 V, and the minimum is VOUT + VDO or 2.7 V, whichever is greater. |
| 2 | GND | power_in | Ground pin, which must be tied to the system ground. |
| 3 | EN | input | Driving EN high turns on the regulator, driving it low puts the regulator into shutdown mode, and EN can be connected to IN if not used. |
| 4 | NR | passive | Fixed-voltage versions only; an external noise-reduction capacitor on this pin bypasses noise generated by the internal band gap and reduces output noise to very low levels. |
| 5 | OUT | power_out | Regulator output, which requires a small ceramic capacitor with total typical capacitance of at least 2 µF from this pin to ground for stability. |
