Application Notes
(1) Depending on the type, load current and connection position (distance from the LA5611) of the external NPN transistor, the
capacitor C7 and resistance R6 is necessary for preventing oscillation.
(2) C1 to C6 are bypass capacitors for preventing oscillation: as such, they must be positioned as close to the LA5611 as possible
in order to stabilize operation.
