R1131X 6 technical notes when using these ics, consider the following points: phase compensation in these ics, phase compensation is made for securing st able operation even if the load current is varied. for this purpose, be sure to use a 1.0 f or more capacitor c out with good frequency characteristics and esr (equivalent series resistance). (note: if a tantalum capacitor is connected to the output pin for phase compensation, if the esr value of the capacitor is too large, the operation mi ght be unstable. because of this, test these ics with as same external components as ones to be used on the pcb.) chip capacitor characteristics of bias dependence an d temperature characteristics may vary depending on its size, manufacturer, and part number. pcb layout make v dd and gnd lines sufficient. if their impedance is high, pick-up the noise or unstable operation may result. connect a capacitor with as much as 1.0mf capacitor between v dd and gnd pin as close as possible. set external components, especially t he output capacitor, as close as possi ble to the ics, and make wiring as short as possible. typical application v dd gnd out R1131X series c2 c1 in out ce ? cm05x5r105k06ab (kyocera) c1005jboj105k (tdk) grm155b30j105ke18b (murata) output capacitor; 1.0 f or more capacity ceramic type (if v out < 1.0v, tantalum type is recommended) input capacitor, 1.0 f or more capacity ceramic type
