The LM380 and LM384 seem to fit the bill better - the LM380 is credited with 2.5W on the data sheet, and the LM3284 was a selected part that could survive a higher supply voltage and was rated for 5W. http://www.ti.com/lit/ds/symlink/lm380.pdf The second part is a voltage regulator, and Bob Widlar managed to corner most of the glory there. -- Bill Sloman, Sydney
