IRU1176CM

Data Sheet No. PD94132 IRU1176 7.5A ULTRA LOW DROPOUT POSITIVE ADJUSTABLE REGULATOR WITH SHUTDOWN INPUT DESCRIPTION The IRU1176 is a 7.5A regulator with extremely low dropout voltage using a proprietary Bipolar process that achieves comparable equivalent on resistance to that of discrete MOSFETs. The IRU1176 also provides a convenient shutdown pin that allows the regulator to be shutdown and reduce the input current consumption. Unlike the PNP type regulators this device does not have high quiescent current during the start up mode making it ideal for applications where there is limited current capability such operation from the 5V standby supply of the computer power supply. One application is the new generation of RDRAM memory that needs to provide 2.5V from 3.3V input and be able to operate from 5VSB as well. FEATURES Guaranteed
