5V Power Supply With Overvoltage Protection.
In this circuit a crowbar scheme is used in which a triac short circuits the power supply and burns the fuse. The burning time of the fuse is not a concern because the power supply is already shorted by the triac and the output voltage will be zero.SparkFun Breadboard Power Supply 5V 3.3V PRT 00114 ...
Here is a very simple breadboard power supply kit that takes power from a DC wall wart and outputs a selectable 5V or 3.3V regulated voltage. The .1" headers are mounted on the bottom of the PCB for simple insertion into a breadboard.PowerBoost 1000 Charger Rechargeable 5V Lipo USB Boost ...

A very good and powerful Regulated Power Supply section was implemented by simply adding a PNP power transistor to the excellent LM317T adjustable regulator chip. In this way this circuit was able to deliver much more than the power required to drive two Mini MosFet amplifiers to full output (at least 2Amp @ 40V into 4 Ohm load) without any appreciable effort.SparkFun FTDI Basic Breakout 5V DEV 09716 SparkFun ...
You can modify the board to make the 5V FTDI a 3.3V FTDI. The trace that connects the 5V pad to the center pad on the back of the 5V FTDI breakout board just needs to be cut with an XACTO hobby knife.Extremely Low Standby Power PSR Switcher AP3984 5V 1A EV1 ...

ESP8266 is a great module for IoT and DIY project specially because of it’s compact size and low cost. However this module works at 3.3v DC, which is not as easy to find as compared to 5v DC supply. So, let’s find out how can we make a very simple 5v to 3.3v step down regulated power supply ...USB Type C DFP Controller and Power Switch with Load ...
