This pin must be connected to ground plane using a low inductance short connection.
The output of the regulator. A minimum of 10 m F capacitor must be connected from this pin
to ground to insure stability.
The input pin of the 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. This pin must always be 1.3V higher than V OUT
in order for the device to regulate properly.

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 of 50 to 100m V and an output capacitance of 500 to 1000 m F. Fortunately as the capacitance
increases, the ESR decreases resulting in a fixed RC time constant. The IRU1050-33 takes advantage of this
phenomena in making the overall regulator loop stable. For most applications a minimum of 100 m F aluminum
electrolytic capacitor such as Sanyo MVGX series, Panasonic FA series as well as the Nichicon PL series insures
both stability and good transient response.
