Fold back current
WebMay 25, 2024 · Foldback current limit is very similar to the standard upper-boundary limit. But the main goal of foldback current is to limit the total power dissipation, keeping the output transistor within its safe power-dissipation limit by reducing the output current limit linearly while V OUT decreases and V IN remains steady. WebThe classic fold back current limit circuit (a transistor pulling down the gate of the pass transistor) doesn't lend itself to easy control via a voltage. here has a good picture of the classic fold back limit circuit. Note: this was submitted earlier, but due to a mistake on my part got lost in the mod que for most of a day. By the time it was ...

The LT3080 is a 1.1A low dropout linear regulator that can be paralleled to increase output current or spread heat in surface mounted ... WebAbstract: An over-current protection circuit for improving the integrated regulators' latch-up effect is proposed. Latch-up effect can be eliminated through combining foldback function with constant current limiting function which could change the slope of the foldback current curve to avoid intersecting the static load line.
