Output current limit

Low dropout voltage: typically 400 mV at 7 A

output current

Output voltage remote sense pin

Fast transient response

Thermal shutdown protection with hysteresis

Wide operating temperature range -40 擄C to

125 擄C

No supply sequencing problems in dual supply

mode

Output voltages available: adjustable

power dissipation in case of insufficient

heatsinking. On chip trimming allows the regulator

to reach a very tight output voltage tolerance,

within 鹵 2 % at the maximum output current and

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
