Precautions

• Wire each pin of VDD, VSS and VOUT carefully in order to set them in low impedance when wiring an IC on a patterned

board.

• In this IC, if load capacitance of the VOUT pin is large, VOUT pin voltage may oscillate. It is recommended not to use an

external capacitor between the VOUT and VSS pin. When using an external capacitor, set near the VOUT pin.

When connecting an A/D converter etc. to the VOUT pin, the input pin capacitance of the A/D converter and the parasitic

capacitance component between wires are included as load capacitance.

To prevent oscillation, it is recommended to use the following output load condition.
