What to Do and What Not to Do
Do not exceed the
Absolute Maximum Ratings
.
Do not exceed the
ESD Ratings
.
Do not exceed the
Recommended Operating Conditions
.
Do not allow the EN input to float.
Do not allow the output voltage to exceed the input voltage, nor go below ground.
Do not use the value of R
θJA
given in the
Thermal Information
table to design your application. Use the information in the
Maximum Ambient Temperature
section.
Follow all the guidelines and suggestions found in this data sheet before committing the design to production. TI application engineers are ready to help critique your design and PCB layout to help make your project a success (see the
サポート・リソース
).
