Regulator Protection
The TPS793xx PMOS-pass transistor has a built-in back diode that conducts reverse current when the input
voltage drops below the output voltage (e.g., during power-down). Current is conducted from the output to the
input and is not internally limited. If extended reverse voltage operation is anticipated, external limiting might be
appropriate.

APPLICATION INFORMATION (continued)
Figure 23. TPS79301 Adjustable LDO Regulator Programming
The TPS793xx features internal current limiting and thermal protection. During normal operation, the TPS793xx
limits output current to approximately 400 mA. When current limiting engages, the output voltage scales back
linearly until the overcurrent condition ends. While current limiting is designed to prevent gross device failure,
care should be taken not to exceed the power dissipation ratings of the package or the absolute maximum
voltage ratings of the device. If the temperature of the device exceeds approximately 165
°
C, thermal-protection
circuitry shuts it down. Once the device has cooled down to below approximately 140
°
C, regulator operation
resumes.
