SYSTEM PARAMETERS [Note 1]

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, TJ = 25

°C, for min/max values TJ is the operating junction temperature range that applies [Note 2],

unless otherwise noted.)
