SYSTEM PARAMETERS (Note 1 Test Circuit Figure 15)
ELECTRICAL CHARACTERISTICS (Unless otherwise specified, Vin = 12 V for the 3.3 V, 5.0 V, and Adjustable version, Vin = 25 V
for the 12 V version, and Vin = 30 V for the 15 V version. ILoad = 500 mA. For typical values TJ = 25°C, for min/max values TJ is the
operating junction temperature range that applies Note 2, unless otherwise noted.)
