µF Ceramic and film capacitors can
be used.
3 Ohm When within this range stable with
all IOUT = 0 mA…50 mA values.

nF 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.

µF Ceramic, tantalum, and film
capacitors can be used. If using a
tantalum capacitor, it should be
checked that surge current rating
is sufficient for the application.
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
potential operating conditions.
