Description
Advanced Monolithic Systems Features AMS2501/AMS2502 1A VERY LOW DROPOUT VOLTAGE REGULATORS Applications • High Efficiency Current Regulators • Post Regulators for Switching Supplies • Audio/Video/Modem Card Supply • Adjustable Power Supply • Notebook/Personal Computer Supplies • Adjustable or Fixed Output 1.5V, 1.8V, 2.5V, 2.85V, 3.0V, 3.3V, 3.5V and 5.0V • Output Current of 1A • Low Dropout, typ. 200mV at 500mA Output Current • Fast Transient Response • Remote Sense 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 1.2 […]
