DESCRIPTION The LD1580 is a very low dropout positive linear voltage regulator particularly suitable in applications requiring output currents up to 7 A. The LD1580 typical dropout voltage is 400mV at 7A while it decreases at lighter loads. This very low dropout is achieved thanks to a second input voltage pin, named VCONTROL, which is also responsable of the output power stage driving. The LD1580 is provided with an output voltage remote sense pin which reduces dramatically any SCHEMATIC DIAGRAM

output voltage variations that could occur due to load changes. On fixed voltage devices, the ADJ pin is still available. A small capacitor on this pin helps to improve transient response.
