LF120CDT-TR from STMicroelectronics, in a DPAK. 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 | GND | power_in | Ground reference pin; the datasheet states the TAB is electrically connected to GND on the DPAK package (Figure 2, page 4), so this pin and the exposed tab form the same ground node. |
| 2 | VOUT | power_out | Regulated output voltage pin; for the LF120C variant VO = 12 V typ (11.76-12.24 V) with output current available up to 500 mA and internal current/thermal limiting (Table 29, page 32). |
| 3 | VIN | power_in | Unregulated DC input supply pin; operating input voltage range up to 16 V at IO = 500 mA (Table 29, page 32), with an absolute maximum DC input of -0.5 to 40 V (device enters shutdown for 18-40 V) per Table 1, page 5. |
