Hi sir ,
I choose the TPS706 fixed output 3.6V for the MCU suppy.
when the input voltage higer than fix output voltage 3.6V , the TPS706 Iq is about 1.5uA .
But when the input voltage lower than fix output voltage 3.6, for example ,the input voltage is 3.5V ,the Iq is about 35uA .
Why the Iq is more than 33uA when the input voltage is lower than LDO fix output ? Thanks!
