I seem to have forgotten the capacitor fundamentals learnt in college...could someone help me clear this out:
I have a micro-controller that gets its supply voltage from a voltage regulator IC. I also have a bypass capacitor to filter the high frequency components of the power supply to gnd. So on the PCB, where should this bypass capacitor be placed, near the Vcc & Gnd pins of the controller or near the Vout pin of the voltage regulator ? What are the trade-offs of one configuration over the other ?
Also please assume that the circuit above has other ICs too (perhaps an EEPROM chip, H Bridge..)
Thanks,
