5A LOW DROPOUT POSITIVE
FIXED 3.3V REGULATOR
DESCRIPTION
The IRU1050-33 is a low dropout three-terminal fixed 3.3V
output regulator with minimum of 5A output current ca-
pability. This product is specifically designed to provide
well regulated supply for low voltage IC applications re-
quiring 3.3V output. The IRU1050-33 is guaranteed to
have <1.3V dropout at full load current making it ideal to
APPLICATIONS provide well regulated output with supply voltage as low
a Standard 3.3V Chip Set and Logic Applications as 4.6V input.

Note 2: Dropout voltage is defined as the minimum dif-
ferential voltage between VIN and Vow required to main-
tain regulation at Vom. It is measured when the output
voltage drops 1% below its nominal value.
Note 3: Minimum load current is defined as the mini-
mum current required at the output in order for the out-
put voltage to maintain regulation. Typically the resistor
dividers are selected such that it automatically main-
tains this current.
