Q? regarding voltage regulator

[yviswanathbe]

Hi,

I want a voltage regulator very urgently.The requirements are

SOT 89 Package
voltage (24-5 V)
Should operate at -55 to +125 degree temperature.
currently i am using 7805 regulator which operates at 0 to 125 degrees temperature.But i need with above range.

any body please help me?

Send me d manufacturers names?


Thanx,

Hi!
Your problem is somwhat very usual...
I think your regulator is enough..
the only thing you do are improving the quality of heatsink and built in colling fan..thats all...
try to use aluminum bars with inch thick....if that is wanted to have....

"The µA78L05AI is characterized for operation over the virtual junction temperature range of –40°C to 125°C .."

Try to get samples from TI ..
