Other Parts Discussed in Thread: TPS7A25, TPS7A91
Hi team,
My customer is considering feed forward cap for noise reduction.
Could you please help my customer calculate feed forward capacitance for TPS7A19 and TPS7A25 respectively? How much CFF is recommended for the condition below?
Vin = 16.4V and Vout = 11.5V. Iout = 0.15A.
I know zero is needed to be placed before unity gain frequency by LDO Basics.
But it doesn't provide specific formula and guideline, so I'd like to learn more that.
Regards,
Itoh
