1 Advanced Monolithic Systems FEATURES.6V to 6V in 1mV increments Voltages Available Active High n/ff Control utput Current of 15mA Quiescent Current of <1 when in Shutdown Low Dropout Voltage of 5mV at 15mA Wide Supply Voltage Range 1.5V to 15V Short Circuit and Thermal Protection Power Good function option Ceramic utput Capacitor K Reference bypass for lower noise AMS311 15mA LW DRPUT VLTAGE REGULATR RoHS compliant APPLICATINS 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 DESCRIPTIN The AMS311 is a 15mA low dropout fixed voltage regulator, featuring an internal electronic switch controlled by TTL or CMS logic levels. When the Enable pin is pulled to a logic high level, the device is in the N state. Designed specifically for battery powered applications where low quiescent current, low dropout and low standby current are required, the AMS311 is ideal to use in standby power systems. Like other regulators the AMS311 series also includes internal current limiting and thermal shutdown. A high precision.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 applications, the AMS311 is available in the 5-pin ST-3 surface mount package and requires only a 1µF capacitor on the output for a minimum amount of external components. The Power Good option is used when the utput Voltage drop must be detected. If the utput Voltage drops by approximately 15% of its nominal value, the open collector on PG pin will pull down to Low state.
