TPS79516DCQR from Texas Instruments, in a SOT-223-6. 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 | EN | input | Enable input, active high and compatible with standard and low-voltage TTL-CMOS levels; drive it low to put the regulator in shutdown, or tie it to IN if shutdown is not needed. |
| 2 | IN | power_in | Input supply to the regulator; recommended VIN is 2.7 V to 5.5 V for the older chip and 2.7 V to 6.0 V for the newer chip. |
| 3 | GND | power_in | Regulator ground pin. |
| 4 | OUT | power_out | Regulator output; a ceramic output capacitor of at least 1 µF from OUT to GND is required for stability. |
| 5 | NR/NC | passive | On the older chip (fixed-voltage versions only) this is the noise-reduction pin, where an external bypass capacitor not exceeding 0.1 µF lowers output noise; on the newer chip this pin is not internally connected (N/C). |
| 6 | GND | power_in | Tab/heat-spreader, electrically connected to GND; solder it to a large ground copper area for thermal performance. |
