AP7 Features General Description.4V Maximum Dropout at Full Load Current Fast Transient Response Output Current Limiting Built-in Thermal Shutdown Good Noise Rejection 3-Terminal Adjustable or Fixed.5V,.8V,.5V, 3.3V, 5.V Lead Free Packages: SOT3-3L, TO5-3L, SOT89-3L, TO63-3L and TO-3L SOT3-3L, TO5-3L and SOT89-3L: Available in Green Molding Compound (No Br, Sb) Lead Free Finish/RoHS Compliant (Note ) AP7 is a low dropout positive adjustable or fixed-mode regulator with A output current capability. The product is voltage specifically designed to provide well-regulated supply for low IC applications such as high-speed bus termination and low current 3.3V logic supply. AP7 is also well suited for other applications such as VGA cards. AP7 is guaranteed to have lower than.4v dropout at full load current making it ideal to provide well-regulated outputs of.5 to 5. with 6.4V to 8V input supply. AP7 is available in commercial temperature grade.

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. 6. 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. 7. 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. 8.
