Regulator Limits Dissipation While Capping Current At The Desired Level
10.08.2017 · Circuits
A current-limiting regulator prevents excessive load current, but it may not prevent excessive regulator dissipation. Many integrated regulators do protect themselves from excessive dissipation and many provide a current limit, yet their current limits may not be at the desired current or may not be sufficiently predictable. This regulator provides predictable output-current and regulator-power limits, as well as undervoltage protection...
