    Voltage regulator for security cam?

    I have a waterproof cctv cam(yellow=video, white=audio, black=power)
    I have no clue who made it but I did find a bad voltage regulator
    part# CJ78L05(datasheet below)
    The replacement comes from china for a total of $6

    I dont want to wait 3-4 weeks so I am looking at another replacement from digikey. I think I have narrowed it down but could use someone help.

    I need to know if I selected the right specs? I think I just need to verify physical size so it fits.

    That's just a "jellybean" 78L05 so any of the SOT-89 package ones should work fine.
    36 Monitors, 3 TVs, 4 Laptops, 1 motherboard, 1 Printer, 1 iMac, 2 hard drive docks and one IP Phone repaired so far....

      Digikey recommended http://www.digikey.com/product-detai...18-1-ND/382184

      I went through my link above and pulled out these SOT-89

      I am only a hobbiest but arent my choices(with Smason's help) better than what they recommended?

        All are suitable -- may as well pick the cheapest...
