Choosing the right voltage regulator
Currently working on the power section of my schematics design. Am using a voltage regulator of 3.3v 500mA. The total power(current) of the board at full load (when operating at full capacity) is 470mA, and the regulator has a drop out or leakage current of about 50mA.
Will it still be ok for me to use this regulator or I should change to another. But the device will not always operate at full capacity, just once in a while. Will it cause any issue on the board. @PCB & Analog @MCU, MPU & Firmware

For butter results and the regulator won't heat up you have to add at least 25-30% that means you're consuming 450mA you should use 563mA - 585mA more is better , also it is recommended to use a heat sync with some thermal paste on it, because the heat effects regulator by time

Its better to go with regulator of higher capacity about 1A. If you have some inductive load then current consumption could be high at startup and this could bring supply voltage down, causing digital circuit to reset or go to error states, so better to go with regulator of 2 to 3 times of peak current
It depends on how long the device will be on at full capacity. Literally I will say you should get another regulator of 1A, which will cover all your power requirements so that there won't be a power flunctuation in your board.
