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 AMS3106 is ideal to use in standby power systems. Like other regulators the AMS3106 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 applications, the AMS3106 is available in the 5-pin SOT-23 surface mount package and 8-pin SOIC. The Power Good option is used when the Output Voltage drop must be detected. If the Output Voltage drops by approximately 15% of its nominal value, the open collector on PG pin will pull down to Low state.
