Supp (V)=5.0 Package=DIP Pins=3 Military=N Click to expand... Can anyone tell me what is this and for what purpose this is used?

Complete data sheet: **broken link removed**. It's a discontinued product. A description of it's function is in the introduction of this document: http://focus.ti.com/lit/an/slva360/slva360.pdf. Here is a data sheet for another device of similar function for reference: **broken link removed**.

I am using PIC18f252 controller, and there is an "BROWNOUT" option for power on reset should i need to connect that external IC or the pic will do that job by using "BROWNOUT" option.
