High current, high accuracy LDO from Diodes Incorporated addresses noise-sensitive power conversion applications
Diodes Incorporated has released a 3A-rated low-dropout (LDO) voltage regulator supporting 4.4 µVRMS operation (at 0.8 V output)...
Limit switches control dc-motor H bridge
You use limit switches to switch off a motor if it reaches one of its two end positions. Even if you build a microprocessor-based motor controller, you should switch off a motor with hardware by building a safety interlock...
Stepper and servo motor tradeoffs
They both have advantages and limitations. So which one is right for your application?
