how to choose the right voltage regulator for my application

Input voltage and output voltage: Ideally, you should know the input voltage range and the required output voltage that you will be working with. Each voltage regulator chip is designed to be used for a specific output voltage. For example, in a device running off 120VAC power that has a 5V Raspberry Pi controller, 12V servo motors and a 24V stepper motor, you would need to use 5V, 12V and 24V voltage regulators to ensure that everything runs smoothly
