SLVS346D September 2003 – December 2019 TPS723
PRODUCTION DATA.
The TPS723 has internal circuitry that monitors and limits output current to protect the regulator from damage under all load conditions. When output current reaches the output current limit (550 mA typical), protection circuitry turns on, reducing output voltage to ensure that current does not increase. See Figure 9 in the Typical Characteristics section.
Do not drive the output more than 0.3 V above the input. An output voltage more than 0.3 V above the input voltage biases the body diode in the pass FET, and allows current to flow from the output to the input. This current is not limited by the device. If this condition is expected, make sure to externally limit the reverse current.
