SL1117A

SL1117A Elektronische Bauelemente RoHS Compliant Product A suffix of “-C” specifies halogen free 1A Low Dropout Positive Adjustable or Fixed-Mode Regulator DESCRIPTION The SL1117A 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. SL1117A is also well suited for other applications such as VGA cards. SL1117A 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.

A min. of 10μF capacitor must be connected from this pin to ground to insure stability. The input pin of regulator. Typically a large storage capacitor is connected from this pin to ground to insure that the input voltage does not sag below the min. dropout voltage during the load transient response. This pin must always be 1.3V higher than VOUT in order for the device to regulate properly.
