1A Low Dropout Positive Adjustable or Fixed-Mode Regulator
Description
The GL1117A is a low dropout at positive adjustable or fixed-mode regulator with minimum of 1A 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 3.3V logic supply. GL1117A is also well suited for other
applications such as VGA cards. GL1117A is guaranteed to have lower than 1.4V dropout at full load current
making it ideal to provide well-regulated outputs of 1.25 to 5.0 with 6.4V to 15V input supply.
