MC79L05ACDR-HXY from HXY MOSFET, 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	-VOUT	power_out	Regulated negative output voltage, nominally -5V. Delivers up to 100mA of output current. Bypass with a 0.1µF capacitor to GND for stability.
2	-VIN	power_in	Negative unregulated input voltage. Operating range -7V to -20V (absolute max -30V). Tie together with the other -VIN pins (3 and 6, 7) and bypass with a 0.33µF capacitor to GND.
3	-VIN	power_in	Negative unregulated input voltage (parallel connection with pins 2, 6, and 7). Operating range -7V to -20V, absolute max -30V.
4	NC	unconnected	No internal connection. Leave floating or tie to a copper island; do not use as a routing tie point.
5	GND	power_in	Common ground reference (0V). For a negative regulator this is the positive/return side of both the input and output loops.
6	-VIN	power_in	Negative unregulated input voltage (parallel connection with pins 2, 3, and 7). Operating range -7V to -20V, absolute max -30V.
7	-VIN	power_in	Negative unregulated input voltage (parallel connection with pins 2, 3, and 6). Operating range -7V to -20V, absolute max -30V.
8	NC	unconnected	No internal connection. Leave floating; not used by the device.
