LT1763 Sense line

Hello RayC,

Yes, you can treat the SENSE pin as an ADJ pin for fixed regulators by adding a resistor divider to the sense line. For LT1763-1.5, the feedback voltage would be 1.5V. You may calculate the resistor divider by considering that SENSE pin on the fixed output parts draws about 10μA regardless of the OUT pin’s voltage. There is an available LTspice model for LT1763 so you can try and simulate this.
