GENERAL DESCRIPTION

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. AMS2502 has an additional feature of an On/Off pin to keep the device in stand-by mode.

The typical load regulation, measured at the Sense pin, for a load current step of 100mA to 1A is less than 1mV.

The AMS2501/AMS2502 series has fast transient response. On 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.
