Hi, SMD tantalums seem to offer a great advantage in terms of size over normal electrolytic caps in stabilising a power supply. However I'm concerned with voltage spikes killing the cap. Basically my application is a small robot with 2 motors (Minimotor 1724 6volts version) with a current draw of around 300mA each, through a MOSFET H-bridge. Power is provided by a LiPo pack providing 7.4V nominal. What I'm concerned about is whether a 47uf 20V SMD tantalum will help stabilise the supply adequately for my 5V LM2940 reg as well as whether motor spikes might kill the cap. Comments anyone?
