... If a tantalum capacitor is used, a lower value of 2.2 F would be adequate important to consider the temperature characteristics of the decoupling capacitors. While Toko regulators are designed to operate as low as -30 C, many capacitors will not operate properly at this temperature. The capacitance of aluminum electrolytic capacitors may decrease low temperatures ...
