Make sure the low ESR capacitor on the power supply
output (usually a tantalum one) is rated at least 10V.
As far as car applications, a spike protection diode
must be inserted close to the power input, in order to
clean the supply from spikes.
A protection diode can be inserted close to the power
input, in order to save the GE864-QUAD V2 from power
polarity inversion. This can be the same diode used
for spike protection.
An example of switching regulator with 12V input is in the
schematic below (split in 2 parts):
