L99VR03 300mA low-dropout (LDO) regulator provides resilient and efficient power, with a wide input-voltage range and very low quiescent current consumption, only 3.5µA at no load. The IC has an enable pin for turning the regulator off, which reduces the idle current to 800nA, and integrates soft-start circuitry to limit current during power-up and fault recovery.

As Bob continues this article series on Mobile App development from an Embedded System’s perspective, he tackles State and State Management in Flutter. As you will see, it is very different from what embedded engineers are used to when we think of state and that misunderstanding can cause no end of trouble if we don’t […] The post Introduction to Flutter State Management appeared first on Circuit Cellar.| Circuit Cellar
Vishay Intertechnology, Inc. introduced a new surface-mount Power Metal Strip® current sense resistor that combines a high power rating up to 5 W, TCR down to ± 75 ppm/°C, and extremely low resistance values down to 0.3 mΩ in the compact 1206 case size. With power ratings 20 times higher than standard resistors in the 1206 […] The post Vishay Intertechnology Power Metal Strip® Resistor Delivers Power to 5 W in Compact 1206 Case Size appeared first on Circuit Cellar.| Circuit Cellar
The simplest way to improve power factor is to add an inductor in series with the circuit. There are big disadvantages to this passive approach. Active approach: add a boost converter between the bridge rectifier and the filter capacitors| Circuit Cellar

In the final part of this series, I discuss the generation of JSON and XML files to send sensor data from the web and database servers to web clients. I also cover upgrading the system from HTTP to HTTPS with the use of an Internet web server on a shared web hosting service. Finally, as a complement to backend development for IoT discussed in the series, I present an example of a frontend web page to graphically display sensor data on a web browser.| Circuit Cellar
