COMPONENTS SELECTION
Input Capacitor
The input capacitor value depends on a lot of factors such as load transient requirements, input source (battery
or DC/DC converter) and its distance from the input cap. Usually a 47
µ
F is enough for any application but a
much lower value can be sufficient in many cases.
Output Capacitor
The output capacitor choice depends basically on the load transient requirements.
Tantalum, Speciality Polimer, POSCAP and aluminum capacitors are good and offer very low ESR values.
