  • 1.3V Maximum Dropout at Full Load Current
  • Fast Transient Response
  • Output Current Limiting
  • Built-in Thermal Shutdown
  • Good Noise Rejection
  • 3-Terminal Adjustable or Fixed 1.8V, 2.5V, 3.3V
  • SOT223-3L and TO252-3L, Packages in “Green” Molding Compound (No Br, Sb)
  • Lead Free Finish / RoHS Compliant (Note 1) APX1117 is a low dropout positive adjustable or fixed-mode voltage regulator with 1A output current capability. The product is specifically designed to provide well-regulated supply for applications such as high-speed bus termination and low current 3.3V logic supply. APX1117 is also well suited for other applications such as VGA cards. APX1117 is guaranteed to have lower than 1.3V dropout at full load current making it ideal to provide well-regulated outputs of 1.25V to 5.0V with 6.3V to 18V input supply.

VOUT O 2 The output of the regulator. A minimum of 10uF capacitor (0.15 Ω ≤ ESR ≤ 20Ω) must be connected from this pin to ground to insure stability. VIN I 3 The input pin of regulator. Typically a large storage capacitor (0.15Ω ≤ ESR ≤ 20Ω) 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 1.3V higher than V OUT in order for the device to regulate properly. Pin Assignments Pin Descriptions

APX1117 contains an internal thermal limiting circui t that is designed to protect the regulator in the event that the maximum junction temperature is exceeded. When activated, typically at 150 °C, the regulator output switches off and then back on as the die cools. Thermal Shutdown 1

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. Load regu lation is measured at the output lead = 1/18” from the package. 5. 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 ove r the full input/output range. 6 . ΔVOUT = 100mV 7. Quiescent current is defined as the minimum out put current required in maintaining regulation. At 12V input/output differential the device is guaranteed to r egulate if the output current is greater than 10mA. 8.
