even

what is difference between 3A adjustable regulator (image above) and this picture (i found it in datasheet LM350) thankyou very much.. ;) ;D the 3A adjustable regulator use R 120 and Rtrim 2K even the C1 and C2 is different with this image. sorry my english is bad.... :( i wanna know pleasseeee...... thankyou very much thankyou

hi thankyou so much. i think there is misunderstanding my camcoder not need 7.5 A but it is a capacity of battery like motorcycle battery. i use itu because i want using my camcoder for long time, my camcoder battery is only 1.1A and it can be approx. 80 minutes so i choose to convert my 12V 7AH battery to voltage level of camcoder. my camcoder general spec: power requirements : 8.4V (1.5A) power consumtions on recording (LCD) : 5.9 W my question is : is it enough if i only use adjustable voltage regulator with lm317T like this schematic

how about this schematic

sorry my electrical is poor i need help to design this project

the camcoder output adaptor is 8.4V 1.5A

i want to convert my 12VDC Battery 7.5 A to 8.4V because i want to use it to my camcoder pls. I was thinking about using voltage divider but can cause drop of voltage and i was thinking about using lm317 but the lm317 Ampere is 1.5A pls help me
