The output of the regulator. A minimum of 10uF capacitor (0.15 ESR 20) must be connected from this pin to ground to insure stability. The input pin of regulator. Typically a large storage capacitor (0.15 ESR 20) 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 VOUT in order for the device to regulate properly. 2 of 8 www.diodes.com MARCH 2008 (c) Diodes Incorporated APX1117 1A LOW DROPOUT POSITIVE ADJUSTABLE OR FIXED-MODE REGULATOR Block Diagram VIN 3 2 VOUT + - + 1.25V CURRENT LIMIT 1 + GND (FIXED) Adj 1 - Thermal Shutdown + Absolute Maximum Ratings Symbol Parameter Rating Unit VIN DC Supply Voltage -0.3 to 18 V TJ Operating Junction Temperature Range 0 to +125 C TMJ Maximum Junction Temperature 150 C PD Power Dissipation SOT223-3L TO252-3L Internally limited by maximum junction temperature of 150C (Note 3) mW TST Storage Temperature -65 to +150 C Notes: 3. APX1117 contains an internal thermal limiting circuit that is designed to protect the regulator in the event that the maximum junction temperature is exceeded. When activated, typically at 150C, the regulator output switches off and then back on as the die cools.

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 regulation 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 over the full input/output range. 6. VOUT = 100mV 7. 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. 8. Test condition for SOT223-3L: TA=27 C, no air flow, 2 oz copper, 5mmX5mm pad. 9.
