i have designed a power supply circuit based on ADP160AUJZ-3.0, the circuit diagram is below
PWR_BATT is Vin = 4.5V
PWR_RTC is Vout = 3.0V
The result is:
1. when load current is 3uA, Iq = 87uA
2. when no load on output port, Iq > 80uA
3. if i cut pin 3 from Vin, and connected to gnd, Iq < 1uA
So i think there must be something wrong with my design. because Iq is more great than spec..
Please help me, thank you.
