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 400 mV at

7 A while it decreases at lighter loads.

This very low dropout is achieved thanks to a

second input voltage pin, named VCONTROL,

which is also responsible of the output power

stage driving.

The LD1580 is provided with an output voltage

remote sense pin which reduces dramatically any

output voltage variations that could occur due to

load changes.

The ADJ pin is still available. A small capacitor on

this pin helps to improve transient response.

The LD1580 also features a built-in output current

limit function and a thermal shutdown protection

with hysteresis which prevents from excessive
