... OUT CURRENT LIMIT The RT9166/A monitors and controls the PMOS' gate voltage, minimum limiting the output current to 350mA for RT9166 and 550mA for RT9166A. The output can be shorted to ground for an indefinite period of time without damaging the part. SHORT-CIRCUIT PROTECTION The device is short circuit protected and in the event of a peak over-current condition, the short-circuit control loop will rapidly drive the output PMOS pass element off ...

Aluminum electrolytics also typically have large temperature variation of capacitance value. Equally important to consider is a capacitor's ESR change with temperature: this is not an issue with ceramics, as their ESR is extremely low. However very important ...

RT9166/A THERMAL CONSIDERATIONS The RT9166/A series can deliver a current 300/ 500mA over the full operating junction temp-erature range. However, the maximum output current must be derated at higher ambient temperature to ensure the junction temperature does ...
