IRU1117-33(PbF)

800mA LOW DROPOUT POSITIVE

FIXED 3.3V REGULATOR

FEATURES

DESCRIPTION

Guaranteed < 1.2V Dropout at 800mA Load

Current

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 DESCRIPTION

Gnd

VOUT

VIN

Ground pin. This pin must be connected to ground plane using a low inductance short

connection.

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.

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.
