10.2.2.3 Configuring LDO Output

Re-arranging Equation 7 and selecting RFB(top) to 2kΩ results in the following:

Equation 20. R F B ( B O T ) = R F B ( T O P ) V O U T V F B - 1

Applying Equation 20 is shown in Equation 21, which results in an RFB(BOT) value of 1kΩ. TI recommends using precision 0.1% resistors for the feedback resistor network.

Equation 21. R F B ( B O T ) = 2 k Ω - 1.8 V - 0.6 V - 1 = 1 k Ω
