DESCRIPTION
The IRU1117-33 is a low dropout three-terminal fixed out-
put regulator with minimum of 800mA output current ca-
pability. This product is specifically designed to provide
well regulated supply for low voltage IC applications such
as VGA, sound & DVD cards. The IRU1117-33 is guar-
anteed to have <1.2V dropout at full load current making
it ideal to provide well regulated with 4.75V to 7V input
supply. The IRU1117-33 is specifically designed to be
stable with low cost aluminum capacitors while main-
taining stability with low ESR tantalum caps.

Note 1: Low duty cycle pulse testing with Kelvin connections is required in order to maintain accurate data.
Note 2: Dropout voltage is defined as the minimum differential voltage between VIN and VOUT required to maintain
regulation at VOUT. It is measured when the output voltage drops 1% below its nominal value.

PIN DESCRIPTIONS
PIN#
1
PIN SYMBOL PIN DESCRIPTION
Gnd Ground pin. This pin must be connected to ground plane using a low inductance short
connection.
2
VOUT
The output of the regulator. This pin is also connected to the tab of the package. An output
capacitor must be connected to this pin to insure stability of the regulator.
3 VIN 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 VOUT in order
for the device to regulate properly.
