rev. 1.10 - 6 - technical notes when using these ics, consider the following points: phase compensation in these ics, phase compensation is made for securing stable operation even if the load current is varied. for this purpose, be sure to use a 2.2 f or more capacitor c out with good frequency characteristics and esr (equivalent series resistance). (note: when the additional ceramic capacitors are connected to the output pin with output capacitor for phase compensation, the operation might be unstable. because 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 line sufficient. when the impedance of these is high, it would be a cause of picking up the noise or unstable operation. connect a capacitor with as much as 1.0 f capacitor between v dd and gnd pin as close as possible. set external components, especially output capacitor as close as possible to the ics and make wiring shortest. test circuits c1 c2 v in a i out c2 = tantal2.2 :*1 c1 = tantal1.0 *1 1 vdd eco 4 out 5 3 ce 2 gnd r1160xxx1x series fig.1 output voltage vs. output current test circuit c1 c2 v c2 = tantal 2.2 f c1 = tantal 1.0 f 1 vdd eco 4 out 5 3 ce 2 gnd r1160xxx1x series fig.2 output voltage vs. input voltage test circuit
