Advanced Monolithic Systems AMS2502
the AMS2502 the reference voltage is brought out to allow the user to add a bypass capacitor for lower noise and transient response improvement. The AMS2501/AMS2502 series are ideal for generating supplies of 1.25V to 3V where both 5V and 3.3V supplies are available. The AMS2501/AMS2502 devices are offered in 8 lead SOIC package.FEATURES

GENERAL DESCRIPTION
The The AMS2501/AMS2502 series of adjustable and fixed low dropout voltage regulators are designed to provide 1A output current. The dropout voltage of the device is 100mV at light loads and rising to 200mV at 500mA output current. A second input voltage of 1.2V or greater than the output is required to achieve this dropout. The AMS2501/AMS2502 can also be used as a single supply device by connecting pin1 and pin 8 together. In this case the dropout voltage will be typically 1.2V. New features have been added to the AMS2501: a remote Sense pin is brought out virtually eliminating output voltage variations due to load changes.
