First, select a value for R1 according to the value recommended in the table 1. Then, R3 is determined. The
output voltage is given by Table 1 for reference. For accurate output voltage, 1% tolerance is required.

Output feed-forward capacitor selection
The AP63201 has the internal integrated loop compensation as shown in the function block diagram. The
compensation network includes an 18k resistor and a 7.6nF capacitor. Usually, the type II compensation
