Posts tagged voltage-regulator

Synonyms: voltage-regulators voltage-stabilizer voltage-stabilizers

Anything related to voltage regulator circuits, both discrete and integrated.

A voltage regulator is a circuit whose purpose is to maintain a constant voltage at its output while providing power to a load.

This tag is also suitable for voltage-reference circuits, which aren't meant to provide much power, but just a very stable output voltage.

This tag doesn't have a detailed wiki yet.

Q&A Are LDOs more efficient than switching regulators in very low currents?

I'm looking for a power supply to power up the VCORE of an mcu. The chip is an STM32 microcontroller (LQFP) and the maximum current it will draw is no more than 150mA. The input will be 3V-5V max...

Q&A Trouble understanding how to use adjustable LDO regulator

The question being asked Ultimately, I want to know why the output voltage wasn't the expected (via calculation) 11.72V when the estimated drop-out voltage at the ~0.1A load was about 200mV. The i...

Q&A Design considerations for a synchronous DC/DC converter

In the field of DC/DC conversion, one can build a synchronous DC/DC converter (also referred to as synchronous rectification). This practice involves replacing a diode with a MOSFET switch. As far...

Q&A Capacitors of voltage regulators [closed]

Assuming we have a voltage regulator : Why do we have to ground Vin and Vout using 2 capacitors just like that?Co could be to provide a low resistance path to GND at high frequencies but what is...
