Other Parts Discussed in Thread: TPS783, , TPS7A05, TPS709
I'm looking for an LDO with ultra low Iq (~500nA like the TPS783) to go from 3.3V to 1.5V where output current isn't an issue. I found the TPS780 which says it has a fixed output voltage version down to 1.5V, but the Recommended Operating Conditions says that the output voltage should be between 1.8 and 4.2 and the product page says it only has a 1.8V fixed option. Which is the correct spec?
If the TPS780 does not work, are there any other LDOs with 500nA Iq that would work? Most of the other options I'm seeing are 1uA Iq like the TPS7A05.
