DESCRIPTION
The IRU1030 is a low dropout three-terminal adjustable
regulator with minimum of 3A output current capability.
This product is specifically designed to provide well regu-
lated supply for low voltage IC applications such as
Pentium
tion for Pentium Pro
cations. The IRU1030 is also well suited for other pro-
cessors such as Cyrix , AMD and Power PC
cations. The IRU1030 is guaranteed to have <1.3V drop-
out at full load current making it ideal to provide well
regulated outputs of 2.5V to 3.3V with 4.75V to 7V input
supply.

APPLICATION INFORMATION Introduction The IRU1030 adjustable Low Dropout (LDO) regulator is a three-terminal device which can easily be programmed with the addition of two external resistors to any volt- ages within the range of 1.25 to 5.5V. This regulator un- ...

Stability The IRU1030 requires the use of an output capacitor as part of the frequency compensation in order to make the regulator stable. Typical designs for microprocessor ap- plications use standard electrolytic capacitors with a typical ESR in the range 100mV and an output 3R2 which capacitance of 500 to 1000mF ...
