AS78L05MTR-G1 from Diodes Incorporated, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	OUTPUT	power_out	Regulated +5 V output, up to 100 mA. Recommended 0.1 µF output bypass capacitor to ground. Output accuracy ±5% over full temperature range.
2	GND	power_in	Ground / common return. Tied internally to the die paddle; multiple GND pins (2, 3, 6, 7) improve thermal dissipation and should all be connected to the ground plane.
3	GND	power_in	Ground / common return. Tied to pins 2, 6, 7 internally; connect all GND pins to the ground plane for thermal performance.
4	NC	unconnected	No internal connection. Leave floating or tie to ground; do not use as a signal net.
5	NC	unconnected	No internal connection. Leave floating or tie to ground; do not use as a signal net.
6	GND	power_in	Ground / common return. Tied to pins 2, 3, 7 internally; connect all GND pins to the ground plane for thermal performance.
7	GND	power_in	Ground / common return. Tied to pins 2, 3, 6 internally; connect all GND pins to the ground plane for thermal performance.
8	INPUT	power_in	Unregulated positive supply input. Absolute maximum 36 V; recommended operating VIN ≤ 30 V for AS78L05. Recommended 0.33 µF input bypass capacitor to ground close to the pin.
