Part Number: TPS53014

Hi, team.

Can I tell you because I got a question about TPS53014?

Voltage of VREG5 is indicated in 5.1V@TYP in the datasheet.

Please also tell me the Minimum and Max values.
※I want to know this information when selection of external MOSFET.

Best regards,

The VREG5 is generated by an internal LDO. The input voltage minimum of 4.5 V is less than the typical LDO output voltage. So for VIN less than 6 V, the LDO VREG5 output voltage may be less than 5.1 V. I doubt that there is any data for it, but I can check tomorrow.

Thank you for contacting me.

Why are you discussing about "when VIN = 4.5V"?

Because it is described in the datasheet as below,
is not MIN / MAX determined by the Individual difference of chips including Line Regulation of 6V <VIN <28V?

First of all, what we want to know is the MIN / MAX value for 5.1 V @ TYP during normal operation.

Best regards,

I found the following simulation data:

VREG5 Output Voltage "IVREG5=0mA,Ta=25℃"

Vin Min Typ Max

4.5   4.38    4.40   4.40
5.5    5.07    5.12   5.13
  12    5.09    5.12   5.13
  28   5.09    5.12   5.13
There is no measured data that I can find.
