产品概述
描述
The LD1580 is a very low-dropout positive linear voltage regulator particularly suitable for 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.
The low-dropout is given by a second input voltage pin, named VCONTROL, which also drives the output power stage.
The LD1580 is provided with an output voltage remote sense pin which reduces drastically any output voltage variation due to load changes.
The ADJ pin is available. A small capacitor on this pin improves transient response.
The LD1580 also features a built-in output current limit function and a thermal shutdown protection with hysteresis which avoids excessive power dissipation in case of insufficient heatsinking. On-chip trimming allows the regulator to reach a very tight output voltage tolerance, within ± 2% at the maximum output current and over the full temperature range.
