Abstract
A voltage regulator includes a pass transistor, an operational amplifier and a voltage divider circuit. The pass transistor receives a supply voltage to generate a regulated output voltage according to a control signal. The operational amplifier generates the control signal according to a feedback voltage. The voltage divider circuit generates the feedback voltage at a feedback node according to the regulated output voltage, and includes a string of resistors and a stabilization element. The string of resistors is coupled to the pass transistor and includes multiple resistors. The stabilization element is coupled to the resistors and receives the regulated output voltage.
