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 10

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.
