TECHNICAL NOTES

When using these ICs, consider the following points:

Phase Compensation

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

purpose, use a capacitor C2 with 0.47

F or more and good ESR (Equivalent Series Resistance).

(Note: If additional ceramic capacitors are connected with parallel to the output pin with an output capacitor for

phase compensation, the operation might be unstable. Because of this, test these ICs with as same external

components as ones to be used on the PCB.)

PCB Layout

as possible.

capacitor, and the line from the capacitor to GND must be wired as short as possible. Please refer to the “Basic Test

Circuit” below.
