Advanced Power Electronics Corp. APE1117 1.2V/1A Low Dropout Fixed-Mode Regulator Features General Description - 1.4V 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 - Low ESR Ceramic Capacitor for output stability - Packages：SOT223, TO252, SOT89 - RoHS Compliant APE1117 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 logic supply. APE1117 is guaranteed to have lower than 1.4V dropout at full load current making it ideal to provide well-regulated outputs of 1.2 with 3V to 12V input supply.

APE1117 1.2V/1A Low Dropout Fixed-Mode Regulator Pin Descriptions NAME I/O PIN # GND I 1 Ground Vout O 2 The output of the regulator. A minimum of 1uF capacitor must be connected from this pin to ground to insure stability. Vin I FUNCTION The input pin of regulator. A minimum of 1uF is connected from this pin to ground to insure that the input voltage does not sag below the minimum dropout voltage during the load transient response. This pin must always be 1.4V higher than Vout in order for the device to regulate properly. 3 Absolute Maximum Ratings Symbol Parameter Vin DC Supply Voltage PD Power Dissipation TST Storage Temperature TOP Operating Junction Temperature Range Rating Unit -0.3 to 12 V Internally Limited -65 to +150 oC 0 to +150 oC Advanced Power Electronics Corp. www.a-power.com.tw 3/6 Advanced Power Electronics Corp.

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.
