Hello i anamol any body help me for LM317 rugulated powersupply
I want to boots out put current (2 -12 volt for 2A ) may i use two LM317 parallel (TO-3 metal pakage) it is use full for that

Hi

See the datasheet at http://www.national.com/ds/LM/LM117.pdf. Page 17 has details of boosting the current capacity using power transistors. The circuit shows the LM117 regulator but should be interchangeable with the LM317.
