Other Parts Discussed in Thread: TLV2217, , UA78
UA78M33C is used for two Main boards.
After the two main boards are placed at - 50°C for 5 minutes, it is powered on. Both UA78M33C have input but no output. When it is gradually heated to - 15°C , it has 3.3V output.
Replace the UA78M33C with TLV2217-33 in these two boards, Two boards can output normally at - 50°C .
Could you please analysis why this happen?
What is the difference between UA78M33C and TLV2217-33?
