TPS732: quiescent current

FRANK1

Part Number: TPS732

Hi Team,

I wanna know more about the parameters in the data sheet.

When the output current is 10mA, is it quiescent state?

As I know about quiescent current, it is the current drawn when the device is enabled and there is no load on the output.
But the Iout=10mA means , there is a load.

Thanks.

Hello,

Yes, you correct in assuming that there is a load when Iout = 10mA and that there is no load on the output when the Quiescent current is defined. The datasheet in the snap you have attached has a typo, it cannot be IQ when Iout = 10mA.

Hi Srikanth ,

Thank you.

what is the value of 'real' quiescent current ? typ. 400uA?

Hello Frank,

Based on the plot in Figure 7 of the Datasheet we can deduce that the Quiescent current (IGND when IOUT = 0) will typically be 250uA- 450uA.
