In most cases you can just use an RC pair to give a suitable delay large enough to handle almost all cases, unless you really need the reset IC. -- Sean At 03:44 AM 1/14/2006, you wrote:

Some LDOs, such as the Micrel MIC5206, has a flag output that goes low if its output voltage isn't OK. This can be tied to /RESET in addition to the RC pair, to give a clean reset in case of brownout. Karl Olsen

Hi Tom,
Any idea of the costing for the IC LTC1985 and do u know of any Reset IC for just 1.8V and not 3 voltages.
Regards,
Jerome

BTW, the LTC1985 allows you to add a push button for the reset. :-)
