Niiyen L7805 Voltage Regulator, 10Pcs/Lot L7805 LM7805 7805 Voltage Regulator Output 5V 1.5A, Linear Positive Fixed, Through Hole Mounted, Fit for Regulated Power Supply & Limiting Circuit

Needed a replacement for a non-working part and they arrived the next day. Soldered it in and I was back in business

13 volts in, none of the 10 gave me 5 volts, all gave 3.5 - 3.6 volts.I chose these for the convenience of next day delivery - it made me hold up my project regardless.

Did not work. I should have read the other reviews. I get less than 1 volt output on these - pure junk. Just wish I had found out sooner , I missed my return window by 2 days.

5V with no load. Falls to 0.4V with 100 ohm (0.05A) load. These don't work.
