LM350AT from Texas Instruments, in a TO-220. 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 | ADJ | input | Adjustment terminal; the regulator holds a nominal 1.25V reference between OUT and ADJ, ADJ pin current is typically 50 µA (100 µA max), and bypassing it to ground improves ripple rejection. |
| 2 | VOUT | power_out | Regulated output (also connected to the tab), adjustable down to 1.2V and capable of more than 3A with a 3A guaranteed current limit and a minimum load current of 3.5 mA typical (10 mA max). |
| 3 | VIN | power_in | Unregulated input; the input-to-output differential must not exceed 35V, and a 0.1 µF disc or 1 µF solid tantalum bypass is recommended. |
