The minimum requirement for the input capacitance is 18.8-pF (4x 4.7-pF) ceramic capacitance, in either a X5R or X7R temperature characteristic, and 100-pF of nonceramic capacitance. Ceramic capacitors should be located within 0.5 inch (1,27 cm) of the regulator's input pins. Electrolytic capacitors must be used at the input in addition to the required ceramic capacitance. The minimum ripple current rating for any nonceramic capacitance must be at least 750 mA rms for output currents of 3 A or less. The ripple current rating of electrolytic capacitors is a major consideration when they are used at the input. This ripple current requirement can be reduced by placing more ceramic capacitors at the input, in addition to the minimum required 18.8-pF. Tantalum capacitors are not recommended for use at the input bus, as none were found to meet the minimum voltage rating of 2 x (maximum dc voltage + ac ripple). This voltage derating is standard practice for regular tantalum capacitors to ensure reliability. Polymer-tantalum capacitors are more reliable, and are available with a maximum rating of typically 20 V. These can be used with input voltages up t0 16 V.
