LDO Feedback Divider
Estimate feedback resistors for an adjustable regulator output.
Input parameters
Results
Confirm the device equation, dropout, stability, and heat.
Model & assumptions
Rupper = Rlower(Vout/Vref − 1); divider current = Vref/Rlower.
Ideal adjustable-LDO feedback divider; ignores reference-pin current. Use the selected regulator equation and allowed resistor range.
