Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
The maximum allowable power dissipation of any T A (ambient temperature) is P D(max) = T J(max) – T A ) / θ JA . Exceeding the maximum
allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
Specification for packaged product only.
Timer High Voltage along with Delay pin current (1μA nom) determines the delay per uF of capacitance. Typical delay is 1.1sec/μf
Discharge current is the current drawn from the output to ground to actively discharge the output capacitor during the shutdown process.
V TARGET is the output voltage of an adjustable with customer resistor divider installed between VOUT and Adj/Sns pin, or the rated output
voltage of a fixed device.
