SYSTEM PARAMETERS ([Note 1] Test Circuit Figure 14)
ELECTRICAL CHARACTERISTICS (Unless otherwise specified, V in = 12 V for the 3.3 V, 5.0 V, and Adjustable version, V in = 25 V
for the 12 V version, and V in = 30 V for the 15 V version. I Load = 200 mA. For typical values T J = 25 ° C, for min/max values T J is the
operating junction temperature range that applies [Note 2], unless otherwise noted.)
