app note: Simple Current-Limiting Power Supply

Posted on Sunday, April 27th, 2014 in app notes by DP


A simple current-limiting power supply from Micrel, app note here.

Just three ICs are required to build this adjustable-voltage, adjustable-current-limit power supply that operates like a laboratory supply. It offers an output voltage range of 0V to 25V and a current limit range of about 10mA to 1.5A. The Micrel MIC29152 LDO Regulator has a ground-referred bandgap (reference) voltage. Other adjustable regulators with ground-based reference voltages should also work.

    I am wondering what kind of transient response this thing has. 330uF at the output seems to be quite large cap…
