DEFINITION AND EXPLANATION OF TECHNICAL TERMS (CONT.)
INPUT-OUTPUT CAPACITORS
In general, the capacitor should be at least 1
μ
F (Aluminum electrolytic) and be rated for the actual ambient operating
temperature range. The table below shows typical characteristics for several types and values of capacitance. Please note
that the ESR varies widely depending upon manufacturer, type, size, and material.

Note: ESR is measured at 10 KHz.
Linear regulators require an output capacitor in order to maintain regulator loop stability. This capacitor should be selected
to insure stable operation over the desired temperature and load range. The graphs below show the effects of capacitance
value and equivalent series resistance (ESR) on the stable operation area.
