Adding capacitor to model railway 12V motor to keep it going over …
$begingroup$ @smokeyone, the capacitor voltage has to be higher than the highest voltage you are going to apply to it. For a 12V system, the capacitor has to be at least 16V. You can use capacitors rated for even higher voltages, just that they are bigger and more expensive. $endgroup$ –
I have a battery that supplies 12V but not regulated and a device that uses 12V regulated, ... So you can use a zener diode to control the voltage. But it will only regulate the overvoltage, so if the voltage drops 12V you will need a big capacitor to mantain the ...

A capacitor with a 12V rating or higher would be used in this case. In another, 50 volts may be needed. A capacitor with a 50V rating or higher would be used. This is why capacitors come in different voltage ratings, so that they can supply circuits with different voltages, fitting the power (voltage) needs of the circuit.
So what''s happening is that on the input side you give the 12V DC input and the IC regulates that voltage and gives an output of ideally 5V (4.8V to 5.2V as per its datasheet). The capacitors are there to smooth out certain spikes due to increased current
