LM340T-5.0 from Texas Instruments, in a TO-220-3. 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 | INPUT | power_in | Input voltage pin accepting supply voltage from 7.5 V to 20 V for proper line regulation producing 5 V regulated output. |
| 2 | GND | power_in | Ground reference pin serving as return path for input and output currents. |
| 3 | OUTPUT | power_out | Output voltage pin providing regulated 5 V output with up to 1.5 A output current capability. |
