Question
What is VCC pin in the ADP2441?
Answer
VCC pin is the output of the internal low dropout regulator. Internal regulator
supplies power for the internal controller and driver circuitry. A 1 µF
ceramic capacitor between VCC and AGND and a 1 µF ceramic capacitor between VCC
and PGND are required respectively for stable operation. A user is not advised
to use this pin as a supply pin and connect to any load on it.
