You’re traveling and you forgot to bring DC to DC converter in your car, but you need it. This simple DC to DC converter […]
Power Supply Circuits
Variable Voltage Regulator based LM117
The regulator circuit uses an LM117K three-terminal adjustable output positive voltage regulator in a TO-3 can. The variable voltage regulator lets you adjust the […]
Variable Zener Diode
This circuit acts like a zener diode with a wide range of voltages. The current passing via the voltage divider R1-R2 is substantially greater […]
Low Voltage Regulators with Short Circuit Protection
These Low Voltage regulators with short circuit protection can provide 6, 7.5, and 9 V from an automobile battery supply of 13.5 V nominal, […]
Lithium Battery Charger
This Lithium battery charger circuit is dedicated to charge lithium batteries. It uses 2 chips, voltage regulator LM317T and ICL7665 warns microprocessors (μPs) of overvoltage and undervoltage conditions.
Low Power Regulated DC to DC Converter
This Low power regulated dc to dc converter circuit obtained by adding a flyback circuit to a square wave oscilator.
Linear Power Supply
Every electronic circuit will work as good as its power supply. However this is often overlooked. There are two main families of power supplies: […]
5V / 4A Regulator Circuit
This is the other power supply regulator circuit, is different from the previous circuit, this using IC op amp quad type MC 3401 operational […]
