IRU1010-33
1A LOW DROPOUT POSITIVE
FIXED 3.3V REGULATOR
FEATURES
DESCRIPTION
Guaranteed < 1.3V Dropout at Full Load Current
Fast Transient Response
The IRU1010-33 is a low dropout three-terminal fixed out-
put regulator with minimum of 1A output current capabil-
ity. This product is specifically designed to provide well
regulated supply for low voltage IC applications such as
VGA, sound & DVD cards. The IRU1010-33 is guaran-
teed to have <1.3V dropout at full load current making it
ideal to provide well regulated with 4.75V to 7V input
supply. The IRU1010-33 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.
