TLV759P: Feedback Resistors Calculation

JH Shin

Part Number: TLV759P
Other Parts Discussed in Thread: TIDA-050027

Hello,

The datasheet for the TLV759P contains the formula for calculating the device feedback resistance as shown below.

Referring to the TIDA-050027 reference design circuit diagram, the TLV759P is used as shown below.

Applying the above formula in the datasheet, the output voltage is 0.66V. Which design guide should users follow?

Thank you.

JH

    Hi JH, 

    Thank you for reaching out and sharing this information with us. 

    You are correct, the FB network provides a 0.66 V rail. 

    The equation shown in the DS is correct. For a 3.3V rail R1 should be 500kOhms and R2 100kOhms, or even 50kOhms and 10kOhms. 

    Best,
