■ Technical Notes on External Components and Typical Application

Phase Compensation

In these ICs, phase compensation is made with 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 the impedance of these is high, current flows, the noise might

be picked up or be a cause of unstable operation. 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)
