GENERAL DESCRIPTION
The AMS1501 series of adjustable and fixed low dropout voltage regulators are designed to provide 1.5A output current to
power the new generation of microprocessors. The dropout voltage of the device is 100mV at light loads and rising to 500mV
at maximum output current. A second low current input voltage 1V or greater then the output voltage is required to achieve
this dropout. The AMS1501 can also be used as a single supply device.
New features have been added to the AMS1501: 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
1.5A is less than 1mV.
The AMS1501 series has fast transient response. The Adjust pin is brought out on fixed devices. To further improve the
transient response the addition of a small capacitor on the Adjust pin is recommended.
The AMS1501 series are ideal for generating power supplies of 2V to 3V where both 5V and 3.3V supplies are available.
The AMS1501 devices are offered in in 5 lead TO-220, 5L TO-263 (plastic DD) and 5L TO-252 (DPAK) packages.
