Hi,

Let me talk about the start up sequence of TPS7A8300.
Is there a recommended startup order for VIN,EN,BIAS pin?
If voltage is applied to EN or BIAS before VIN,
Is there a problem?

Could you give me your advice?

Best Regards,

Hi Yusuke-san,

Vbias and Vin can be sequenced in any order; however, Ven must be either tied to Vin or be applied after Vin for proper operation.

Very Respectfully,
Ryan
