TPS61021A: Maximum leakage current into Vout pin during shut down

Part Number: TPS61021A
Other Parts Discussed in Thread: TPS61021EVM-723,

Hi,

What is the typical and maximum shutdown current into the VOUT pin (EN low, Vin 3.0V, Vout 3.3V, Tj -40, +25 and +85°C)?

Dear Sir,

When EN=L, Vout will drop to zero!

Dear Helen,

Yes, it will drop to zero. But what is the drain current causing the voltage drop?
Current drain caused by the feedback is specified but not leakage current into VOUT pin.

With the TPS61021EVM-723 I measure 9uA current into VOUT TERMINAL (3.3V from other power supply), approx 7uA is related to the feedback hence 2uA is drained into VOUT pin.

What is the expected behaviour of the VOUT pin when TPS61021A is disabled?
What is the temperature dependency of the leakage current into VOUT pin?

Best Regards
