Abstract: Voltage regulators use capacitors to compensate the voltage regulator and provide stable performance. Capacitors have an inherent equivalent series resistance (ESR) that changes over various operating conditions including signal frequency, operating temperature as well as others. An apparatus and method compensates for the low ESR of capacitors to increase the total equivalent series resistance of the capacitor. By providing an “on-chip” resistance between the capacitor and the circuit ground potential, minimum total ESR can be provided such that stable load regulation is achieved with capacitors that would otherwise be undesirable for such use. Increasing the value of the output capacitor's equivalent series resistance allows wider ranging values of capacitance to be used. The increased range of capacitance values allows capacitors of different material types to be used.
