TPS7A21-Q1: Output Voltage Tolerance Definition

Part Number: TPS7A21-Q1

Tool/software:

Hi TI Expert,

I would like to clarify the definition of the ΔVOUT marked in the TPS7A21-Q1 datasheet.

In first row, assume the VOUT is 4V, the VOUT range will be (4V*97.75%) ~ (4V *101.5%)?

That will be 3.91V~4.06V, am I right?

In the forth row, assume VOUT is 2V, the VOUT range will be 1.93V ~ 2.05V?

For the Line regulation:

Assume VOUT= 3V, ΔVin = 1V (5V VIN -> 4V VIN), the IOUT = 1mA.

The ΔVOUT will be 0.03% * 1V * 3V = 0.9mV, so VOUT will be (3V + 0.9mV) or (3V - 0.9mV)?

For the load regulation,

Assume VOUT = 3V, ΔIOUT = 200mA(from 1mA -> 201mA), I believe the VOUT will be 3V - (3V * 0.003% * 200) = 2.982V?

Please correct me if I was wrong.

Thank you.
