On all models of raspberry pi since the raspberry pi b 2014 except the zero range there is low voltage detection circuitry that will detect if the supply voltage drops below 4 63v 5.
Raspberry pi 3 b power supply.
One switch mode regulator for the core voltage as well as a linear one for the lpddr2 memory supply.
Raspberry pi 4 case.

Usage depends on what you re doing with the pi.
1 4ghz 64 bit quad core processor dual band wireless lan bluetooth 4 2 ble faster ethernet and power over ethernet support with separate poe hat.
The raspberry pi boards typically draw much lower amounts between 200 and 500ma.
The official and recommended usb c power supply.

The bcm2835 processor chip found on the original raspberry pi model b and b as well as on the zero products has on chip power supplies.
The power supply included in this kit incorporates a noise filter to provide the highest stability and comes with a 5 foot cable.
Earlier models demanded a lower draw of 5v at 1a but in practice greater amperage is usually preferable.

For low power projects you can reduce the amperage quite a bit before it affects performance or stability.
Raspberry pi 15 3w usb c power supply.
The recommended amount is between 700ma for a raspberry pi model a and up to 2 5a for a raspberry pi 3 model b see power supply requirements in the magpi issue 56 page 39.
Raspberry pi 3 model b.
Raspberry pi 3 model b.
The pi 3 has a recommended power supply of 5 1v at 2 5a which covers most situations.
Raspberry pi 3 model b.
The official case for raspberry pi 4.
This will result in a warning icon being displayed on all attached displays and an entry being added to the kernel log.
