For adjustable LDO - TLS205B0EJV,  the input voltage range is -

And the output voltage range is -

This is little bit confusing, how is the output voltage is only 1.19 to 1.25 ?

I need 5V output, for that the dropout voltage will be 320mV as below datasheet snap -

Is it correct, so that min. VI = 5 + 0.32 = 5.32V @ IQ = 500mA?

 

Can anyone help me here.

Hello Abhishek, 

Yes, you are right. 


The adjustable version of the TLS205B0 has an output voltage range of 1.22 V(typical) to 20 V - VDR. The output voltage is set by the ratio of two external resistors, as it can be seen in the below figure.

The below-highlighted values show the min output values with tolerance. (min of min, typical of min, max of min)
