Capacitor Selection

Ceramic capacitors with low equivalent series resistance (ESR) are recommended to achieve low output voltage ripple. X5R and X7R-type dielectrics are recommended for the stable capacitance versus temperature characteristics and DC bias. Higher DC bias results in decreased capacitance based on the capacitors specifications. Use a minimum of two 4.7-µF capacitance for CIN and a 10-µF for CBYP. Making this capacitor value too large can prevent proper start-up operations. Evaluating the Bode plot of the circuit under normal operation can provide insight on the stability of the system.
