8.2.2.5 Determine f0 and calculate RC
Use Equation 20 to and calculate RC. A higher RC value shows faster transient response in cost of unstableness. If the transient response is not enough even with high RC value, try increasing the out put capacitance. The recommended f0 value is fOSC/4.
Equation 20. 
Equation 21.
