Can anyone identify this 8-pin DFN SMD component?
Marking is:
LAAS
N819
417

\$\begingroup\$ That's DFN, not QFN. \$\endgroup\$– HearthCommented Dec 8, 2023 at 15:10

Possibly Analog Devices LTC1540.
The LTC1540 is an 8-pin DFN package, size 3x3mm. The datasheet indicates the first line of the marking should be LAAS:
With no further details about what the circuit does and he surrounding components and dimensions, this is purely a best guess.
It seems promising as pins 1 and 2 (V- and GND) appear to go to a large plane from your image, and pin 7 (V+) goes to a thick trace which could be a power feed.

\$\begingroup\$ Pin n°1 marking is typical of Linear Tech (Analog devices) +1 \$\endgroup\$– vivierCommented Dec 9, 2023 at 20:17
