AAT2120 Overview
The AAT2120 SwitchReg is a 1.8MHz step-down converter with an input voltage range of 2.7V to 5.5V and output as low as 0.6V. Its low supply current, small size, and high switching frequency make the AAT2120 the ideal choice for portable applications. The AAT2120 delivers up to 500mA of load current, while maintaining a low 45μA no load quiescent current.
