IRU1015-33
1.5A LOW DROPOUT POSITIVE
FIXED 3.3V REGULATOR
DESCRIPTION
The IRU1015-33 is a low dropout three terminal fixed
3.3V output regulator with minimum of 1.5A output cur-
rent capability. This product is specifically designed to
provide well regulated supply for low voltage IC applica-
tions requiring 3.3V output. The IRU1015-33 is guaran-
teed to have <1.3V dropout at full load current making it
ideal to provide well regulated output with supply voltage
as low as 4.6V input.
FEATURES
Guaranteed < 1.3V Dropout at Full Load Current

Gnd
This pin must be connected to ground plane using a low inductance short connection.
VOUT
The output of the regulator. A minimum of 10µF capacitor must be connected from this
pin to ground to insure stability.
3
VIN
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 drop out
voltage during the load transient response. This pin must always be 1.3V higher than VOUT
in order for the device to regulate properly.

APPLICATION INFORMATION
Stability
The IRU1015-33 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 100mΩ and an output capacitance of 500 to 1000µF. Fortunately as the capacitance
increases, the ESR decreases resulting in a fixed RC time constant. The IRU1015-33 takes advantage of this
phenomena in making the overall regulator loop stable. For most applications a minimum of 100µF 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.
