1) For temporary, transitional voltage drop or voltage rising phenomenon,

the IC is liable to malfunction should the ratings be exceeded.

2) Where wiring impedance is high, operations may become unstable due to noise and/or phase lag

Care shall be taken for capacitor selection to ensure stability of phase compensation from the point of ESR influence.

5) Regarding the input transient response, the undershoot at the output voltage might be larger when input voltage

variation is 5.0V or larger and the through-

rate is 0.5V/μs or higher.

If the undershoot is not acceptable, please increase the output capacitance value and evaluate the system on your PCB

well.

6) The IC goes into “undefined state” if the CE pin is not connected (Open state).

The CE pin voltage should be fixed in low or high for stable operation.

7) In general, semiconductor components have a possibility to have variation of electrical specifications due to the (cosmic)

radiation exposure. Therefore this product has the same possibility. Please inform us in advance if your system might

have a possibility to be exposed to the (cosmic) radiation in the production process (assembly, test, etc.).

8) Torex places an importance on improving our products and their reliability.

We request that users incorporate fail-safe designs and post-aging prevention treatment

when using Torex products in their systems.
