Hello,
I'm facing some difficulties understanding a circuit for dropping 7.5V to 5V using TLV1117-50. I couldn't find the circuit for TLV1117-50 (the fixed value package) so using the circuit for adjustable package found on page 11 of its datasheet http://www.ti.com/lit/gpn/tlv1117-50 suggests resistors' and capacitors' value. Here is the circuit:
My questions are:
1. Am I right to take this circuit as the reference even so it's for an adjustable package not the fixed 5V output package? Or there are specific circuits better to follow?
2. Seeing the VOUT equation suggested below the reference circuit:
VOUT = VREF(1 + (R2/R1)) + (IADJ * R2)
how to define R1 and R2 values?
Thanks for taking a look.
