Typical Applications
For all applications use capacitors with low effective series resistance (ESR) to maintain
a low dropout voltage with high stability, good conversion efficiency and a low p-p
voltage ripple.
An additional capacitor in the supply line (between
V
CC
and
V
SS
) is useful to reduce the
AC input impedance. As a consequence, this minimize the spurious signals (EMI) on the
supply lines, that came from the current peaks when the BGV503 is switching. The value
of this capacitor depends on the circuit configuration and on customer requirements
concerning EMI; 1
μ
F is regarded as sufficient.
