... Rev. 1.4 08/01/02 5A LOW DROPOUT POSITIVE FIXED 3.3V REGULATOR DESCRIPTION The IRU1050- low dropout three-terminal fixed 3.3V output regulator with minimum of 5A output current ca- pability. This product is specifically designed to provide well regulated supply for low voltage IC applications re- quiring 3.3V output. The IRU1050-33 is guaranteed to have <1.3V dropout at full load current making it ideal to provide well regulated output with supply voltage as low as 4 ...

... APPLICATION INFORMATION Stability The IRU1050-33 requires the use of an output capacitor as part of the frequency compensation in order to make the regulator stable. Typical designs for microprocessor applications use standard electrolytic capacitors with a typical ESR in the range 100mV and an output capacitance of 500 to 1000mF. Fortunately as the capacitance increases, the ESR decreases resulting in a fixed RC time constant ...
