PRODUCTION DATA
The devices require input decoupling capacitors on power supply input VIN. Also, bulk capacitors are needed depending on the application. The minimum input capacitance required is given in Equation 7.
TI recommends using high-quality X5R or X7R input decoupling capacitors of 30 µF on the input voltage pin VIN. The voltage rating on the input capacitor must be greater than the maximum input voltage. The capacitor must also have a ripple current rating greater than the maximum input current ripple of the application. The input ripple current is calculated by Equation 8:
A 1-µF ceramic capacitor is needed for the decoupling capacitor on the VCC pin.
