Since it has superior dropout characteristics compared to regular LDOs, it can be used to supply 2.5V on moth- erboards or 1.5V, 1.8V on peripheral cards from the 3.3V supply thus allowing the elimination of costly heatsinks. An enable pin further reduces power dissi- pation while shut down. The G965 provides excellent regulation over variations in line, load and tempera- ture. The G965 is available with 1.5V, 1.8V and 2.5V inter- nally preset outputs that are also adjustable using ex- ternal resistors. Ordering Information ORDER NUMBER ORDER NUMBER (Pb free) MARKING TEMP.
