Abstract :
A current limiting circuit applied in low dropout linear voltage regulator is designed and simulated. It can limit the maximum output current and the output short current of the regulator within 320mA and 30mA, respectively, and well realize the purpose of overcurrent protection. Prototype of the circuit can be fabricated using the 0.5μm CMOS process.
