1000 F of external non-ceramic output capacitance is required for basic operation. Adding additional capacitance at the load further
improves transient response. Up to 1000 F of ceramic capacitance may be added in addition to the required non-ceramic capacitance.
See the Capacitor Application Information section and the TuboTrans Technology section for more guidance.
(7)
This is the calculated maximum when not using TurboTrans technology. This value includes both ceramic and non-ceramic
capacitors. The minimum ESR requirement often results in a lower value of output capacitance. See the Capacitor Application
Information section for further guidance.
(8)
When using TurboTrans technology, a minimum value of output capacitance is required for proper operation. Additionally, low ESR
capacitors are required for proper operation. See the TurboTrans Technology section for further guidance.
