(6) 300 µ F of ceramic output capacitance is required for basic operation. The minimum output capacitance requirement increases when
TurboTrans™ (TT) technology is utilized. Additionally, low ESR capacitors are required for proper operation. See related Application
Information for more guidance.
(7) This is the calculated maximum disregarding TurboTrans™ technology. When the TurboTrans™ feature is utilized, the minimum output
capacitance must be increased.
