MAX8902A/MAX8902B
Input Capacitor
A 10µF ceramic capacitor is recommended for the
input. Select a capacitor that maintains its capacitance
over temperature and DC bias. Capacitors with X5R or
X7R temperature characteristics generally perform well.
Output Capacitor
A minimum of 10µF of capacitance is required at OUT
to ensure stability. Select a ceramic capacitor that
maintains its capacitance over temperature and DC
bias. Capacitors with X5R or X7R temperature charac-
teristics generally perform well.
