Dear Sir/Madam,
Not sure whether here is the correct forum I should post my question here.
Refer to datasheet https://nvhs.files.wordpress.com/2013/02/datasheet-l9110.pdf
From the above test table, the input voltage is 9V but the output is 7.5 ~ 7.7V, may I assume there is about 1.3 ~ 1.5V is being consumed by the module L9110? If I expect the final output is 3V, then should I provide the input voltage at around the range 4.3 ~ 4.5V? Is it the same if my desired output is at 5V and I simply add 1.5V more as the input voltage? If not, how do I estimate the input voltage I should provide?
Best regards,
Kelvin.
