Hello,
About input capacitor, TPS7A6950-Q1 datasheet page 17 explains as follows.
But, Figure 22. Typical Application Schematic use 1uF input capacitor.
< Page 17 >
8.2.1.2.1 Input Capacitor
The typical recommended value for the decoupling capacitor is 10 µF.
I understand that input capacitance requirement depend on pattern length (impedance) between input power supply and load transient.
Please advise if there is any other concern when I use 1uF input capacitor.
Best Regards.
