TDA2050ADTR from XBLW, in a TO-263-5L. 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+ | input | Non-inverting input of the amplifier. |
| 2 | IN- | input | Inverting input of the amplifier. |
| 3 | -Vs | power_in | Negative supply pin; supply voltage is ±4.5V to ±25V (absolute maximum ±25V). |
| 4 | OUT | output | Amplifier output; peak output current is internally limited to 5A absolute maximum. |
| 5 | +Vs | power_in | Positive supply pin; supply voltage is ±4.5V to ±25V (absolute maximum ±25V). |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
