TPS7A8033DRBR 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; a 4.7-μF or larger capacitor of any type is required for stability. |
| 2 | OUT | power_out | Regulator output; a 4.7-μF or larger capacitor of any type is required for stability. |
| 3 | FB/SNS | input | For the fixed-output version this pin is the output voltage sense (SNS) input, which should be connected close to the load to minimize trace resistive drop. |
| 4 | GND | power_in | Ground reference for the regulator. |
| 5 | EN | input | Driving EN high turns the regulator on and driving it low puts it into shutdown; EN must not be left floating and can be connected to IN if not used. |
| 6 | NR | passive | Connect an external capacitor between NR and ground to reduce output noise to very low levels and to slow the VOUT ramp (RC soft-start). |
| 7 | IN | power_in | Unregulated input supply to the regulator. |
| 8 | IN | power_in | Unregulated input supply to the regulator. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
