Linear Regulator Frequently Asked Questions: What Is Current Limit Foldback?

Tony Bonte - Design Manager Jul 11th 2013
Q: What is current limit foldback? A: This is a current limiting technique to limit the peak power dissipation to prevent thermal destabilization or thermal runaway in the power transistor (which usually leads to the part destroying itself), to keep it in its SOA (safe operating area). As an example, see the current foldback ...
