STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2(DPAK)
LF120ABDT-TR from STMicroelectronics, in a TO-252-2(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 | VI | power_in | DC input voltage supply pin; operating voltage range 13 to 16 V for full performance with up to 500 mA output current. |
| 2 | GND | power_in | Ground reference and output current return path; electrically connected to the package tab. |
| 3 | VO | output | Regulated 12 V output (±1% tolerance: 11.88 to 12.12 V at 50 mA, VI = 15 V, 25°C); capable of 500 mA continuous output with 1 A internal current limit. |
