Regulator Protection
The TPS730xx PMOS-pass transistor has a built-in back diode that conducts reverse current when the input
voltage drops below the output voltage (for example, 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.

Figure 17. TPS73001 Adjustable LDO Regulator Programming
The TPS730xx features internal current limiting and thermal protection. During normal operation, the TPS730xx
limits output current to approximately 400mA. 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.
