LD1580
7A Very low drop positive voltage regulator adjustable and fixed
Features

Output current limit Low dropout voltage: typically 400mV at 7A output current Output voltage remote sense pin Fast transient response Thermal shutdown protection with hysteresis Wide operating temperature range -40 C to 125 C No supply sequencing problems in dual supply mode Output voltages available 1.5 V, 2.5 V, 3.3 V, adjustable 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. On fixed voltage devices, 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 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.

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 responsible of the output power stage driving.
