ZD
ESD-Zener diode: 6.1 V typ., max 5 mA; RST(ON) < 380 at 1.6
mA, ESD zener diodes are not to be used as voltage clamp at DC
conditions. Operation in this mode may result in a drift of the zener
voltage (increase of up to 1 V).

13) Power Transistor off, high impedance
14) with external resistor between pin 3 and pin 5
15) An external short of output to Vbb, in the off state, causes an internal current from output to ground. If RGND is used, an offset
voltage at the GND and ST pins will occur and the VST low signal may be errorious.
16) Low resistance to Vbb may be detected in ON-state by the no-load-detection
