Advanced Power Electronics Corp. APE8912/APE8913 1.2V/1.32V 1A LOW DROPOUT FIXED-MODE REGULATOR FEATURES DESCRIPTION 1.5V 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 APE891X is a low dropout 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 1.2V/1.32V logic supply. APE891X is guaranteed to have lower than 1.5V dropout at full load current making it ideal to provide wellregulated outputs of 1.2/1.32 with 3V to 6V input supply.

See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing. Note2. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the difference between input and output differential and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range. Note3. Quiescent current is defined as the minimum output current required in maintaining regulation. 2 Advanced Power Electronics Corp. APE8912/APE8913 PIN DESCRIPTIONS PIN SYMBOL PIN DESCRIPITON The input pin of the regulator. A minimum of 1uF connected from this pin to ground to insure that the input voltage does not VIN sag below the minimum dropout voltage during the load transient response. This pin must always be 1.5V higher than VOUT in order for the device to regulate properly. GND Ground The output of the regulator. A minimum of 1uF capacitor VOUT (10mΩ < ESR < 1Ω) muse be connected from this pin to to ground to insure stability. BLOCK DIAGRAM 3 Advanced Power Electronics Corp.
