Advanced Monolithic Systems AMS3101 150mA LOW DROPOUT VOLTAGE REGULATOR RoHS compliant FEATURES 0.6V to 6V in 100mV increments Voltages Available Active High On/Off Control Output Current of 150mA Quiescent Current of <1µA when in Shutdown Low Dropout Voltage of 250mV at 150mA Wide Supply Voltage Range 1.5V to 15V Short Circuit and Thermal Protection Power Good function option Ceramic Output Capacitor OK Reference bypass for lower noise APPLICATIONS Battery Powered Systems Cellular Phones Cordless Telephones Portable (Notebook) Computers Portable Instrumentation Portable Consumer Equipment Personal Communication Equipment Radio Control Systems Low Voltage Systems MP3 Player GENERAL DESCRIPTION The AMS3101 is a 150mA low dropout fixed voltage regulator, featuring an internal electronic switch controlled by TTL or CMOS logic levels. When the Enable pin is pulled to a logic high level, the device is in the ON state. Designed specifically for battery powered applications where low quiescent current, low dropout and low standby current are required, the AMS3101 is ideal to use in standby power systems. Like other regulators the AMS3101 series also includes internal current limiting and thermal shutdown. A high precision 0.6V voltage reference enables the device to provide very low output voltages. A key feature includes a reference bypass pin to improve its low-noise performance for fixed output versions. Ideal for space critical applica...
