ELECTRICAL CHARACTERISTICS (continued)
(V+ = +15V, GND = PGND = 0V, SYNC = REF, I
Note 1: Since the reference uses VL as its supply, V+ line-regulation error is insignificant.
Note 2: At very low input voltages, quiescent supply current may increase due to excessive PNP base current in the VL linear
