| Zusammenfassung: | Disclosed is a low dropout regulator that uses a load current tracking zero circuit to stabilize a feedback loop to prevent oscillations. The load current tracking zero circuit senses the DC component of the current flowing through the pass transistor of the low dropout regulator and uses the pass transistor current signal to control a multiplicative factor. The multiplicative factor multiplies the AC variations in the output voltage to generate the zero current. |
