app note: Simple Current-Limiting Power Supply

MICREL_AP19

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…

  • Drone: So these go for around $330 USD and NO published calibration procedure online or otherwise? Given what's inside - I don't think I'll be considering...
  • Pekka Akselin: This is ridiculous!? :-) We are back at 256(!) byte EPROMs that needed multiple, a handful, of voltages to run! :-(
  • KH: Let's try a back-of-envelope calc balancing energies. From MCP1700 datasheet, there are graphs for a 200mA load step. Estimate the energy shortfall as 12uJ. Say...
  • Daniel: It's been a week and my comment is still awaiting moderation. Apparently the CIA doesn't want their involvement known?
  • KH: Agree, so okay, I guess he must have learned from somewhere. 100nF and 1000uF is so far apart, that was jarring; it's more magic incantation...
