Abstract
A power supply circuit (1), particularly for a microcontroller of a transmission control unit, comprises a first output (3) supplying a first output voltage (UOUT1) and a second output (4) supplying a second output voltage (UOUT2), the first output voltage (UOUT1) being different from the second output voltage (UOUT2). The power supply circuit (1) also comprises a unit (OP1, T2, OP2, T3) adjusting the first (UOUT1) and second output voltage (UOUT2) and a controller (OP3-OP5, T2, T3) limiting the voltage difference between the first (UOUT1) and second output voltage (UOUT2).
