TPS27081A: Vout in OFF state

Part Number: TPS27081A
Other Parts Discussed in Thread: TPS22919

Hello experts,

When TPS27081A is in OFF state, how much is Vout?
From datasheet, it is described as Vout is not equal to Vin.
(Basically, I believe Vout=0V in OFF state)

Thanks and best regards,
Ryo Akashi

    Akashi-san,

    This device does not have any integrated output discharge function. This means that the output is left in a highZ state when disabled.

    If there is capacitance on the output, then the output will not always fall to 0V.

    If you are looking for output = 0V when device is OFF, please look at our devices with integrated quick output discharge (QOD) like TPS22919.
