Description
1A Low Dropout Positive Adjustable or Fixed-Mode Regulator
The GJ1117A 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. GJ1117A is also well suited for other applications such as VGA cards. GJ1117A 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 12V input supply.
Features
