Why recommend tantalum over ceramic capacitor for voltage
The LM1117 voltage regulator datasheet recommends using tantalum capacitors on the input and output. What is the reason for this? What advantage does tantalum have over a ceramic capacitor? A 10μF tantalum capacitor costs about 21 cents, while a 10μF ceramic capacitor costs about 3 cents. The ceramic capacitor is also a bit smaller physically.
Why does a capacitor discharge slowly?
Not exactly. The voltage v(t) across the capacitor decays with the time constant RC because the internal resistance of the DVM is across the capacitor when it is measuring the capacitor voltage. The time constant is RC, so a bigger capacitance means that the capacitor voltage takes longer to decay towards zero.
