If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected.1.The maximum allowable power dissipation at any T A (ambient temperature) is P Dmax = (T Jmax – T A) / θJA. Exceeding the maximum allowablepower dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.Table 3.

Extended exposure to stresses beyond the Recommended Operating Ranges limits may affect device reliability.2.The device is not guaranteed to work outside its operating rating.Pin FunctionVIN is the supply pin for both the LDO’s operation and the load the LDO is driving. It is recommended that a 1 m F ceramic bypass capacitor be placed between the V IN pin and ground in close proximity to the device. When using longer connections to the power supply, C IN value can be increased without limit. The operating input voltage range is from 3.3 V to 13 V .FLT is an active low open −drain output indicating one of 3fault conditions:1.Input under −voltage: V IN is below the intendedand/or the ground plane of the PCB. Connection to the ground plane enhances thermal conductivity drawing heat out of the package and into the surrounding PCB.ILIM stands for Current Limit and is the control input for setting the point at which the current limit is invoked. I LIMis defined as the current at which V OUT is still within 80%of its nominal value and should not be confused with I SC , the short circuit current, measured at V OUT = 0 V , which is typically 100 mA greater than I LIM .A resistor R EXT placed between I LIM and GND selects the trip current according to a formula:I LIMIT +I LIMIT0)Current_Limit_Factor(CLF)R EXT(eq. 1)I LIM0 is the built −in minimum current limit (typically 150 mA), and CLF is a numerical value (typical 30,000V olts) which relates the allowable load current to a (eq. 2)(eq. 3)m F ceramic (eq. 4)−temp VOUT is protected against the application of voltages greater than VIN. For example, in automotive applications,if CAT6202 is powering a remote load and damage occurs to a wiring harness shorting a powered line, Battery + for instance, to VOUT, CAT6202 will not be damaged by this higher voltage being applied to VOUT.Table 4.
