NOTES:
3. This parameter refers to the saturation resistance of the MOS pass transistor. The minimum input-output voltage differential at low current (under
5mA), can be determined by multiplying the load current (including set resistor current, but not quiescent current) by this resistance.
4. This output has a positive temperature coefficient. Using it in combination with the inverting input of the regulator at VSET, a negative
coefficient results in the output voltage. See Figure 9 for details. Pin will not source current.
5. All pins are designed to withstand electrostatic discharge (ESD) levels in excess of 2000V.
6. All significant improvements over the industry standard ICL7663 are highlighted.
