(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 t he output capacitor c2, as close as possible to the ics, and make wiring as short as possible.
