1 Description Pin Assignments 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. is also well suited for other applications such as VGA cards. 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. The input pin of regulator. Typically a large storage capacitor 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.

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. 3. 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. 4. 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. 5. Test conditions for SOT89-3L, TO5-3L, TO-3L, and TO63-3L: Devices mounted on FR-4 substrate, single sided PC board, oz copper, with minimum recommended pad layout, no air flow. 6.
