Having more decoupling capacitance on the board will increase inrush current as well, as all the capacitors have to be charged up once power is connected. Using larger decoupling capacitors than necessary might mean you'll have to add measures to decrease inrush current where you'd otherwise not need to.

- dragontamer 2y agoSoftstart is often good design though and shouldn't be too hard anymore. How many circuits cannot afford 100us of softstart? I guess to your point though: 100uF of capacitance (because of a lot of 10uF caps) to 3.3V requires a 3.3Amp softstart over those 100us startup time. So you still can't go crazy spammy. While 100x 100 nF caps is only 10uF all together.
