Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18” from the package. 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. At 12V input/output differential the device is guaranteed to regulate if the output current is greater than 10mA. 3 Advanced Power Electronics Corp. APE1117L PIN DESCRIPTIONS PIN SYMBOL ADJ/GND PIN DESCRIPTION A resistor divider from this pin to the V OUT pin and ground sets the output voltage. (Ground only for Fixed-Mode) VOUT The output of the regulator. (Note1,2) 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 minimum VIN 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. (Note1) Note1: To prevent oscillation, a 4.7uF minimum X7R or X5R dielectric is strongly recommended if ceramics are used as output capacitors. Note2: A minimum of 4.7uF EL capacitor to 100uF must be connected from this pin to ground to insure stability.
