AX1113

400mA Low Dropout Linear Regulator



GENERAL DESCRIPTION

AX1113 is a low dropout positive adjustable or fixed-mode regulator with minimum of

400mA output current capability. The product is specifically designed to provide

well-regulated supply for low voltage IC applications such as high-speed bus termination

and low current 5V logic supply. AX1113 is also well suited for other applications such as

VGA cards. AX1113 is guaranteed to have lower than 1.2V dropout at full load current.
