Part Number: BQ21040
I am trying to build a GPS device with battery backup for cars
My charger IC BQ21040, powered via LDO TL751M (input 12v and output 5v) .Battery size 150mah.
Every thing works fine but the LDO is getting heated up to 50-60 degrees , it is normal ?
LDO will generate heat this is normal, a switching buck converter would be lower heat for 12V-5V.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
