5V 3 Amp Fixed Voltage Regulator Circuit using IC LM123
In this article I have explained the main specifications, datasheet and circuit application notes of the IC LM123, LM323 which are precision 5V, 3 amp fixed voltage regulator IC. These ICs can be used for generating highly regulated 5 V output with a an impressive 3 amp current output. The maximum input to the IC […]
IC 555 Automatic Emergency Light Circuit
The discussed 2 simple IC 555 based emergency lamp system employs just a single IC 555 and yet is able to switch more than 20 LEDs directly, it will illuminate the LEDs only during the absence of mains power and ambient light. 1) Using IC 555 as a Comparator The proposed circuit is not only […]
Automatic Micro UPS Circuit
The following article discusses a simple automatic micro UPS circuit which can be used with modems for acquiring uninterrupted power from a DC source, and battery during mains power failures. The circuit also incorporates an automatic over charge cut off, and a low battery indication feature. The circuit was requested by Mr. Kapil Goel. Technical […]
3 Simple DC UPS Circuits for Modem/Router
In the following article I have explained 3 useful DC to DC uninterruptible power supply circuits or DC UPS circuits for low DC to DC uninterruptible power applications The first idea below presents a DC UPS circuit can be used for providing back up power to modems or routers during mains failures, so that the broadband/WiFi […]
Energy Saving Automatic LED Light Controller Circuit
In this post I have explained an interesting energy saving lighting circuit design which switches ON only when it is logically required thus helps to save electricity, and also increases the working life of the whole system. Technical Specifications Hello Swagatam, Thanks for response, the details which you asked are as such , 1. solar […]
