TPS736125DRBR from Texas Instruments, in a SON-8-EP(3x3). 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 | OUT | power_out | Regulator output; the device is stable without an external output capacitor. |
| 2 | N/C | unconnected | No internal connection on the DRB package; the pin is shown as N/C in the pin figure. |
| 3 | NR/FB | passive | On fixed-voltage versions this is NR, where an external noise-reduction capacitor to GND lowers output noise; on the adjustable version it is FB, the error-amplifier feedback input that sets the output voltage. |
| 4 | GND | power_in | Ground; the exposed thermal pad is also listed with this pin and should be connected to the ground plane for heat dissipation. |
| 5 | EN | input | Drive high to enable the regulator and low to place it in shutdown mode; if shutdown is not needed, connect EN to IN. |
| 6 | N/C | unconnected | No internal connection on the DRB package; the pin is shown as N/C in the pin figure. |
| 7 | N/C | unconnected | No internal connection on the DRB package; the pin is shown as N/C in the pin figure. |
| 8 | IN | power_in | Regulator input supply, operating from 1.7 V to 5.5 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
