APE8913N

Advanced Power Electronics Corp. Features - 1.2V maximum dropout at full load current - Fast transient response - Output current limiting - Built-in thermal shutdown - Needs Only 1uF Capacitor for stability - Good noise rejection - 3-Terminal Fixed 1.2V/1.32V - Low ESR Ceramic Capacitor for output stability - Packages：SOT23 - RoHS Compliant APE8912N/APE8913N Pb Free Plating Product 1.2V/1.32V 0.4A Low Dropout Fixed-Mode Regulator General Description A PE891 X i s a low dropout f ixed-mode regulator with minimum of 0.4A output current capability. The product is specifically d esigned to provide well -regulated supply for low voltage IC applications such as high-speed bus termination and low current 1.2V/1.32V logic supply. APE891X is guaranteed to have lower than 1.2V dropout at full load current making it ideal to provide well-regulated outputs of 1.2V/1.32V with 2.4V to 6V input supply.

A minimum of 1uF capacitor must be connected from this pin to ground to insure stability. Ground The input pin of regulator. A minimum of 1uF is connected from this pin to ground to i nsure that the input voltage does not sag below t he minimum d ropout voltage during the load transient response. This pin must always be 1.2V higher than Vout in order for the device to regulate properly.
