(5)
A minimum value of external output capacitor is required for proper operation. Adding additional capacitance at the load further improves
transient response. See the Capacitor Application Information section for more guidance.
(6)
This is the calculated maximum. This value includes both ceramic and non-ceramic capacitors. The minimum ESR requirement often
results in a lower value. See the related Application Information for more guidance.
(7)
This is the minimum ESR for all the electrolytic (nonceramic) capacitance. Use 5 m
as the minimum when using manufacturer's
max-ESR values to calculate.
(8)
Minimum capacitance will be determined by your transient deviation requirement. A corresponding resistor, RTT is required for proper
operation. See the TurboTrans Selection section for guidance in selecting the capacitance and RTT value.
(9)
This is the calculated maximum. This value includes both ceramic and non-ceramic capacitors.
(10) When calculating the Capacitance × ESR product use the capacitance and ESR values of a single capacitor. For an output capacitor
bank of several capacitor types and values, calculate the C × ESR product using the values of the capacitor that makes up the majority
of the capacitance.
