AAT1121 Overview
The AAT1121 SwitchReg is a 1.5MHz 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 AAT1121 the ideal choice for portable applications. The AAT1121 delivers 250mA of load current, while maintaining a low 30µA no load quiescent current.
