LP38691-Q1: Different dropout voltages

Part Number: LP38691-Q1

Hello TI,

I am calculating worst case power dissipation for the device LP38691-Q1. I have come across different dropout voltages in the datasheet. I would like to calculate worst case power dissipation from -40 to +125 which is full operating temperature range of the device. below are the different dropout voltages that i came across in the datasheet. I request you to clarify the same. I want to calculate PD at output voltage 5V and load current 325mA. Input voltage range is 5V to 9V.

Here its mentioned 250mV at 500mA. I assume this is at 25degC

Here it says 450mV at full operating temperature range

Below figure has different values. I believe its for 1.8V output voltage.

Could you please clarify ?
