Characteristics The
l denotes the specifications which apply over the full operating junction temperature range. Conditions are VNTC = VADJ = VCC, VLBSEL = GND, TJ = 25В°C unless otherwise specified. Current into a pin
is positive and current out of a pin is negative. All voltages are referenced to GND unless otherwise noted. (Note 2)
