r1170x 8 technical notes on external components and typical application phase compensation in these ics, phase compensation is made with the out put capacitor for securing st able operation even if the load current is varied. for this purpose, use as much as 10f capacitor as c l . if you use a tantalum type capacitor and esr value of the capacitor is large, output might be unstable. evaluate your circuit with considering frequency characteristics. further, refe r to the typical characteristics no. 12. mounting on pcb make v dd and gnd lines sufficient. if their impedance is hi gh, a current flows, the noise picked up or unstable operation may result. further use as much as 10f capacitor between v dd pin and gnd pin as close as possible. set an output capacitor between v out pin and gnd pin for phase compensation as close as possible.
