PRODUCTION DATA.
The internal current limit circuit is used to protect the LDO against high load-current faults or shorting events. During a current-limit event, the LDO sources constant current; therefore, the output voltage falls with decreased load impedance. Thermal shutdown can activate during a current limit event because of the high power dissipation typically found in these conditions. For proper operation of the current limit, minimize the inductances to the input and load. Continuous operation in current limit is not recommended.
