AIP78L05 from Wuxi I-core Elec, in a SOT-89. 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 | OUTPUT | power_out | Regulated output pin (输出); the datasheet states a maximum output current of 100 mA in normal application and an absolute maximum of 150 mA. |
| 2 | COMMON | power_in | Common terminal (公共端) serving as the ground reference for the regulator. |
| 3 | INPUT | power_in | Unregulated input pin (输入); the datasheet gives an input supply voltage rating of 7.0 to 30 V. |
