TECHNICAL NOTES

When using these ICs, consider the following points:

PCB Layout

Connect a capacitor with a capacitance value as much as 1.0

and as close as possible to the pins.

Set the output capacitors C2 and C3 for phase compensation, as close as possible to the ICs, and make

wiring as short as possible.

Phase Compensation

In these ICs, phase compensation is made for securing stable operation even if the load current is varied.

For this purpose, connect capacitors with a capacitance value as much as 1.0

µF or more as C2 and C3 with

close as possible to the pins.

If you use a tantalum type capacitor and ESR value of the capacitor is large, output might be unstable.

Evaluate your circuit with considering frequency characteristics.

Depending on the capacitor size, manufacturer, and part number, the bias characteristics and temperature

characteristics are different. Evaluate the circuit with actual using capacitors.
