GENERAL DESCRIPTION
The AMS3106 is a 500mA 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 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.
