AS78L05Z-E1 from Diodes Incorporated, in a TO-92. 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 5V output of the AS78L05, rated up to 100mA when adequate heat sinking is provided, with output voltage specified at 4.8V to 5.2V. |
| 2 | GND | power_in | Ground reference pin that returns both the input and output currents of the regulator. |
| 3 | INPUT | power_in | Unregulated supply input with an absolute maximum rating of 36V and regulation specified for 7V to 20V input in the electrical characteristics. |
