(see the psrr vs. frequency graph in the typical performanc e characterist ics). input capacitor selection use a 1f c apacitor on the input of the MP2009 . larger values will help to improve line transie nt response with the drawback of increased size . cera mic ca pacitors are preferred, but tantalu m capacitors ma y also suffice. output cap acitor selection the mp200 9 is designe d specifica l ly to work wi th very low esr ceramic o u tput capacitor in space - limiting and performan ce consider ation. output capacitor of larger values will help to improve load transie nt response and reduce noise wit h the drawback of increa sed size. a 1f ceramic capacitor with esr lower than 3 ? is sufficient f o r the MP2009 application circuit.
