AS78L05CZTR-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 delivering up to 100mA, with 0.01µF minimum load capacitance recommended to limit high frequency noise. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | INPUT | power_in | Unregulated input voltage, recommended 7V to 30V for the AS78L05 with an absolute maximum of 36V. |
