Dear team,
Is the voltage of VIN which VCC LDO needs more than 6.2V?
Our customer is going to make the output of 5V from 3.3V - 5V input.
In this case is another power supply necessary for VIN?

Dear Sir,
In this condition, the VCC voltage is around 5Vo-0.2V=4.8V. 0.2V is voltage drop across the LDO.
Thank you for comment,
When Vin=3.3-5V and Vout=5V, Vcc connects with Vout, but it do not satisfy Vout>Vin.
Is there any problem?

0.2V is a draft value, it is around 0.15V-0.25V, generally should be around 0.2V.
