AMS2501数据手册Advanced Monolithic Systems中文资料规格书

描述 Description

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 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. The typical load regulation, measured at the Sense pin, for a load current step of 100mA to 1A is less than 1mV. The AMS2501 series has fast transient response.
