AMS1505V series of adjustable and fixed ultra low dropout voltage regulators, designed specially for video applications where a very low dropout is critical, provide 5A output current to power the new generation of high speed video cards. The dropout voltage of the device is 200mV max. at 3A loads and rising to 350mV at maximum output current. A second low current input voltage 1.2V or greater then the output voltage is required to achieve this dropout. New features have been added to the AMS1505V: a remote Sense pin is brought out virtually eliminating output voltage variations due to load changes. The typical load regulation, measured at the Sense pin, for a load current step of 100mA to 5A is less than 1mV. The AMS1505V series has fast transient response. To further improve the transient response the addition of a small capacitor on the Adjust pin is recommended. The AMS1505V series are ideal for generating supplies of 2V to 3V on boards where both 5V and 3.3V supplies are available. The AMS1505V devices are offered in 5 lead TO-220 and TO-263 (plastic DD) packages.
