Abstract
A low drop out (LDO) voltage regulator () includes a pass transistor (MP) having a source coupled by an output conductor () to a load and a drain coupled to an input voltage to be regulated. An error amplifier () has a first input coupled to a reference voltage, a second input connected to a feedback conductor (A), and an output coupled to a gate of the pass transistor. A parallel path transistor (MP) has a source coupled to the input voltage, a gate coupled to the output () of the error amplifier (), and a drain coupled to the feedback conductor. A feedback resistor (R) is coupled between the feedback conductor and the output conductor.
