GENERAL DESCRIPTION
The
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.
