■ Technical Notes on External Components and Typical Application

Phase Compensation

In these ICs, phase compensation is made with the output capacitor for securing stable operation

even if the load current is varied. For this purpose, use as much as 10µF Capacitor as C^L.

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. Further, refer to the

Typical Characteristics No.12.

Mounting on PCB

Make VDD and GND lines sufficient. If their impedance is high, current flows, the noise pick-up or

unstable operation may result. Further use as much as 10µF Capacitor between VDD pin and GND

pin as close as possible.

Set an Output capcitor between VOUT pin and GND pin for phase compensation as close as possible.

(Refer to the example of typical application)
