When using these ICs, consider the following points:
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 0.47µF or more ceramic capacitor COUT.
(Test these ICs with as same external components as ones to be used on the PCB.)
When a tantalum capacitor is used with this IC, if the equivalent series resistor (ESR) of the capacitor is large,
output voltage may be unstable.
Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result.
Connect a capacitor with as much as 1.0µF capacitor between VDD and GND pin as close as possible.
Set external components such as an output capacitor, as close as possible to the ICs and make wiring as
short as possible.
Ex. : C1: Ceramic Capacitor 1.0µF
C2 : Ceramic Capacitor 0.47µF (Murata GRM40B474K)
