... OM9551SP, OM9552SP, OM9553SP, OM9554SP Vin(+4.5- 5.5) (optional) 0.1uF COM Internal to the package is a 22uF input capacitor and a 330uF output capacitor. The Omnirel process allows sufficient space allocation to include all components necessary to complete the basic regulation design. The additional by-pass capacitors are suggested if an improvement in switching noise becomes necessary. ...
