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 10F Capacitor as CL.
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, a current flows, the noise picked up or unstable
operation may result. Further use as much as 10F capacitor between VDD pin and GND pin as close as
possible.
Set an Output capacitor between VOUT pin and GND pin for phase compensation as close as possible.
