AMS3109 Micropower 700mA Low Noise Fast Transient Response LDO General Description The AMS3109 is a high performance linear regulator with very low dropout voltage and excellent transient response. It is designed to operate with wide input voltage range of 1.5 – 12Volts making it ideal for two step conversion while maintaining high efficiency for many power sensitive applications. The device is capable of supplying 700mA of output current with a typical dropout voltage of 550mV. The product is available in adjustable output voltage. The linear regulator has been optimized for noise sensitive applications. The device includes an Enable pin for electrical on/off of the regulator. Forcing the Enable pin to logic low shuts down the LDO and reduces the supply current below 1µA.
