I'm a relative electronics newbie (A-Level, 15 years ago, not much since).. ..I was wondering why you would choose one type of capacitor over another in given applications. I notice that the example cct on a datasheet for the LM317LZ vreg specifies 0.1uF electrolytic, but has onother in a different part of the circuit that isn't electrolytic. Why might that be?
