Electrical Characteristics: VCC = 15V, RT = 8.2kΩ, CT = 3.3nF, for typical values TA=25˚C, for min/max values TA is the operating
ambient temperature range that applies [Note 3].

Note 1: Maximum package power dissipation limits must be observed.
Note 3: Adjust VCC above the Start-Up threshold before setting to 15V.
Note 4: This parameter is measured at latch trip point with VFB=0V.
Note 6: These parameters are guaranteed by design but not 100% tested
in production.
Note 7: Low duty cycle pulse techniques are used during test to main-
tain junction temperature as close to ambient as possible: Tlow=0°C ;
Thigh=+70°C
