... Rev. 1.2 11/29/99 7.5A ULTRA LOW DROPOUT POSITIVE ADJUSTABLE REGULATOR DESCRIPTION The IRU1175 is a 7.5A regulator with extremely low drop- out voltage using a proprietary bipolar process that achieves comparable equivalent on resistance to that of discrete MOSFETs. This product is specifically designed to provide well regulated supply for applications requir- ing very low dropout such as 2 ...

... Vctrl=2.75V, Vin=2.05V, Vadj=0V 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. IRU1175 MIN TYP MAX UNITS 15 ...

... Output Voltage Setting The IRU1175 can be programmed to any voltages in the range of 1.25V to 5.5V with the addition of R1 and R2 external resistors according to the following formula: V ...

... Load Regulation Since the IRU1175 has separate pins for the output (V out ) and the sense (V sense ), it is ideal for providing true re- mote sensing of the output voltage at the load. This means that the voltage drops due to parasitic resistance such as PCB traces between the regulator and the load are compensated for using remote sensing ...
