Zusammenfassung:	Using a burn-in operational amplifier (opamp) for a phased locked loop (PLL) regulator including activating a voltage stress mode for an integrated circuit comprising a PLL regulator for a PLL, wherein the PLL regulator comprises thin-oxide transistors, and wherein activating the voltage stress mode for the integrated circuit comprises applying an elevated voltage to an input of the PLL regulator; and enabling, during the voltage stress mode, a burn-in opamp coupled to the input of the PLL regulator, wherein enabling the burn-in opamp bias the input of the PLL regulator to a voltage lower than the elevated voltage.
