A typical example of a switch-mode power supply is that based on the LM2671 or LM2674. The components for it are available for outputs of 3.3 V, 5 V and 12 V. There is also a version providing a ...

For example, 12 volts is commonly used for drives, while 3.3v and 5v are used by the chips and other motherboard components. Switching Power Supplies.

For Raspberry Pi 4, it was recommended to use a power adapter that can supply 5V/3A power, but for Raspberry Pi 5 , which began shipping on October 23, 2023, a 5V/5A power adapter is now a ...

The DJI Power 1000 supports 5V and 5A according to the specifications, but the voltage may go up or down depending on the cable, and it may not be possible to fully operate a 5V/5A compatible device.

For 5V output, use a 5.6V zener diode, for example. IC 3, R 1, R 2, and V 1 form the feedback circuit to set the output voltage. The output-voltage equation is V OUT =V 1 (R 1 /R 2 +1). The TL431 is a ...

Your 1.5A 7805 will limit to about 200mA if shorted. This is really useful. Switching regulators, however, have a different way and may push a lot more current in case of a fault.
