... IRU1120CP Rev. 1.3 08/20/02 DESCRIPTION The IRU1120 is an adjustable linear voltage regulator packaged in a 5-pin ultra thin-pak surface mount pack- age. The adjustable output voltage can be set from 1.25V and up using a simple resistor divider. The input power can be supplied by a single 5V supply. The regulator is capable of supplying 2 Amps of continuous current with an input voltage of 5V ...

... The IRU1120 provides Over Current Protection when the output current exceeds typically 3A. The output de- creases to limit the power dissipation. Stability The IRU1120 requires the use of an output capacitor as part of the frequency compensation in order to make the regulator stable. A minimum input capacitance of 4.7mF and a minimum output capacitance 4.7mF Ceramic ca- pacitor is needed for regulator stage as well as the speci- fied minimum loads to guarantee stability ...
