LP2954AIT 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 | IN | input | Unregulated input voltage pin; the datasheet gives a 30 V maximum input supply voltage and provides reverse battery protection on this pin. |
| 2 | GND | power_in | Ground pin for the regulator. |
| 3 | OUT | output | Regulated output voltage pin that requires an output capacitor to maintain stability, with capacitor details given in the Detailed Design Procedure. |
