Hello,
I have a question regarding LDO regulators. What is the difference between quiescent current (Iq) and ground current (Ignd).
Based on the graphs in figures 9 and 10 below (for the TPS7A27), they are very different. However, in TI’s document SLVA079 (also shown below), it is implied that they are the same thing. I have found other documentation that also say this. So, what is ground current and which specification should I be focused on for low power battery operated devices?
Thanks!
Connor
