1) Threshold at which the current limitation starts to operate. This threshold is only active when VCC3 is configured for stand-
alone configuration.
2) Tolerance includes load regulation and line regulation.
3) At Tj > 125°C, the power transistor leakage could be increased, which has to be added to the quiescent current of the
application independently if the regulator is turned on/off. To prevent an over-voltage condition at no load due to this
increased leakage, an internal clamping structure will automatically turn on at typ. 200mV above the upper limit of the
programmed output voltage.
4) Not subject to production test, specified by design.
5) a) Ratio will change depending on the chosen shunt resistor which value is correlating to the maximum power dissipation
of the PNP pass device. See Chapter 8.4 for the ratio calculation. The ratio will also change at low-drop operation.
For supply voltages of 5.5V < VS < 6V the accuracy applies only for a total load current of 250mA.
The load sharing ratio in SBC Stop Mode has +/-10% wider limits than specified.
b) The output voltage precision in load sharing in SBC Stop Mode is according to VCC1 +/-4% or better for loads up to
20mA and +/-2% with loads greater than 20mA.
In SBC Normal the +/-2% precision for 5V/3.3V tolerance is valid regardless of the applied load.
