Note   1:  All voltages are with respect to the V
NEG
 pin voltage.
2:  The leakage currents on the ENABLE and RESTART
 pins are strongly dependent on the applied voltage level. The spec-
ified levels represent normal operating conditions. Higher leakage current may be measured at different input voltages.
3:  Negative current is defined as coming out of the pin.
