TLV757P: TLV757P

Dear all,

I am looking for voltage regulator with following requirement. Vin 5V, Vout 4V and Vout 3.3V.

My Application is to supply and DC bias for RF amplifier.

I came across TLV757P and found that its has output voltages that i need. However, i am confused about how i can achieve different output voltages (4V and 3.3V)? because it says fixed, then it also shows different output options with no specific part number for each variation?

Thanks and regards,
