File Size : 116 KB Manufacturer:FREESCALE Description:Introduction The IRU1261 is a dual fixed output Low Dropout (LDO) regulator available in a 5-pin TO-220 or TO-263 pack- ages. This voltage regulator is designed specifically for PentiumII processor applications requiring 2.5V and 1.5V supplies, eliminating the need for a second regulator re- sulting in lower overall system cost. The IRU1261 is de- signed to take advantage of 5V supply to provide the drive for the pass transistor, allowing 2.5V supply to be generated from 3.3V input. This feature improves the power dissipation of the 2.5V regulator substantially al- lowing a smaller heat sink to be used for the applica- tion. Compared to the IRU1260 dual adjustable regula- tor, the IRU1261 includes the resistor dividers that are otherwise needed with the IRU1260, eliminating four ex- ternal components and their tolerances, resulting in a more accurate initial accuracy for each output voltage. Other features of the device include: fast response to sudden load current changes, such as GTL+ termina- tion application and thermal shutdown protection to pro- tect the device if an overload condition occurs.
