Bias generators with ultralow noise and ripple for sensitive circuits
https://www.electronics-lab.com/bias-generators-with-ultralow-noise-and-ripple-for-sensitive-circuits/
The LT®3095 generates two low-noise bias supplies from a common input voltage ranging from 3V to 20V. Each channel includes a fixed frequency, peak current-mode step-up switching regulator and a low-noise, singleresistor- programmable 50mA linear regulator. The linear regulator’s high power supply ripple rejection (PSRR) combined with its low-noise performance results in less than 100μVP-P […]

Power supply IC generates low-noise bipolar (+/-) power rails
https://www.electronics-lab.com/power-supply-ic-generates-low-noise-bipolar-power-rails/
by Graham Prophet @ edn-europe.com: LTC3265 is a high voltage, highly integrated, low noise dual output power supply IC which takes a single positive input supply (VIN_P) and generates low noise bipolar rails up to ±2•VIN_P without any inductors. High voltage boost and inverting charge pumps deliver low noise dual outputs with post-regulating ±50 mA LDOs […]
Automatic Light Switching System with Dimmer
https://www.electronics-lab.com/automatic-light-switching-system-with-dimmer/
Manual switching of outdoor lights in houses or roadways can be sometimes really inconvenient especially when we are far away or still at work. Sometimes this becomes an opportunity for thieves to infiltrate houses or a possibility of accident in roadways if night comes and our outdoor lights are still OFF. That is why the […]
How to control LM2596 buck-converter with microcontroller
https://www.electronics-lab.com/how-to-control-lm2596-buck-converter-with-microcontroller/
by hugatry @ hackvlog.com: Every now and then someone asks on different forums if there is an way to control cheap LM2596 modules with an Arduino or another microcontroller. I decided to demonstrate one solution that might be basic electronics for some, but still many don’t know about. Those buck converters will change the output voltage […]
