When the output capacitor (CL) is large, there is a possibility that the output voltage will be unstable. * If a tantalum or electrolytic capacitor is used for the output capacitor (CL), ripple voltage will increase, and there is a possibility that operation will become unstable. Test fully using the actual device. * When Schottky Diodes, which have a large junction capacity are used, there is a possibility that the output voltage will be unstable. ＜Output voltage (VOUTSET) setting＞ Output voltage can be set by adding an external resistor. Output voltage is set by the following equation according to RFB1, RFB2, VFB and VREF. VOUTSET = VFB - RFB1 / RFB2 × ( VREF - VFB ) Please select within 100kΩ ≦ RFB1 + RFB2 ≦ 500kΩ range.
