300mA Low Noise CMOS LDO
Function Description (Continue)
Thermal Protection Shutdown
The thermal protection shutdown function protects the device from operating in over temperature condition. When the
junction temperature exceeds +160^oC, the thermal sensor signals the shutdown logic, turning off the pass transistor
and allowing the IC to tool down. The thermal sensor turns the pass transistor on again after the IC’s junction
temperature drops to +140^oC.
Soft-Start Circuitry
The TS9007 includes a soft-start circuitry to limit inrush current at turn-on. During power up, the output capacitor and
output load are charged with a reduce output current. Shortly after the initial power up, the soft-start feature is
terminated and normal operation is resumed.
