* Required if regulator is located far from power supply filter.
** C
must be at least 22μF to maintain stability. May be increased without bound to maintain regulation during transients. Locate as close as possible to the
OUT
regulator. This capacitor must be rated over the same operating temperature range as the regulator and the ESR is critical; see curve.
