1 Lead-free AP Features General Description.3V maximum dropout at full load current Fixed.V±% output voltage Fast transient response Output current limiting Built-in thermal shutdown Good noise rejection Packages: SOT3-3L, TO5-3L, SOT89-3L SOT3-3L and TO5-3L: Available in Green Molding Compound (no Br, Sb) (Note ) Lead Free Finish/RoHS Compliant (Note ) AP is a low dropout positive fixed-mode regulator with A 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.v logic supply. AP is also well suited for other applications such as VGA cards. AP is guaranteed to have lower than.3v dropout at full load current making it ideal to provide well-regulated outputs of. output voltage with.5v input voltage supply.

A minimum of uf capacitor (.5Ω ESR Ω) must be connected from this pin to ground to insure stability. I 3 The input pin of regulator. Typically a large storage capacitor (.5Ω ESR Ω) 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.3v higher than Vout in order for the device to regulate properly.

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 = /8 from the package. 5. Line and load regulation are guaranteed up to the maximum power dissipation of 5W. 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. Quiescent current is defined as the minimum output current required in maintaining regulation. At V input/output differential the device is guaranteed to regulate if the output current is greater than ma. 7. Test condition for SOT89-3L: no air flow, no heat sink. 8.
