1. The selected capacitor has to
meet the minimum capacitance
requirement in all operating
conditions.
2. Ceramic and film capacitors
can be used.
3. The value of CL should be
smaller than or equal to the
value of CIN.
1. When within this range, stable
with all IOUT = 0 mA…150 mA
values.
1. Ceramic and film capacitors are
best suited. For maximum
output voltage accuracy DC
leakage current through
capacitor should be kept as low
as possible. In any case DC
leakage current must be below
100 nA.
1. A big enough input capacitance
is needed to prevent possible
impedance
interactions
between the supply and
MAS9124.
2. Ceramic, tantalum, and film
capacitors can be used. If a
tantalum capacitor is used, it
should be checked that the
surge current rating is sufficient
for the application.
3. In the case that the inductance
between a battery and
MAS9124 is very small
(< 0.1 µH), a 0.47 µF input
capacitor is sufficient.
4. The value of CIN should not be
smaller than the value of CL.
1. The device should always be in
the ON state if VOUT(NOM) = 5 V.
Values given on the table are minimum requirements unless otherwise specified. When selecting capacitors, tolerance and temperature
coefficient must be considered to make sure that the requirement is met in all operating conditions.
