LD1580 7 A very low drop adjustable positive voltage regulator Datasheet - production data Description 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. P PAK The low-dropout is given by a second input voltage pin, named V , which also drives CONTROL the output power stage. The LD1580 is provided with an output voltage remote sense pin which reduces drastically any Features output voltage variation due to load changes. Output current limit The ADJ pin is available. A small capacitor on this Low-dropout voltage: typically 400 mV at 7 A pin improves transient response. output current The LD1580 also features a built-in output current Output voltage remote sense pin limit function and a thermal shutdown protection Fast transient response with hysteresis which avoids excessive power dissipation in case of insufficient heatsinking. On- Thermal shutdown protection with hysteresis chip trimming allows the regulator to reach a very Wide operating temperature range: from -40 C tight output voltage tolerance, within 2% at the to 125 C maximum output current and over the full No supply sequencing problems in dual supply temperature range. mode Output voltage available: adjustable Table 1.
