(note: if additional ceramic capacitors are connected with parallel to the output pin with an output capacitor for phase compensation, the operation might be unstable. becaus e of this, test these ics with as same external components as ones to be used on the pcb.) pcb layout make v dd and gnd lines sufficient. if their impedance is hi gh, noise pickup or unstable operation may result. connect a capacitor c1 with a capacitance value as much as 1.0 f or more between v dd and gnd pin, and as close as possible to the pins. set external components, especially the output capacitor c2, as close as possible to the ics, and make wiring as short as possible.
