A linear voltage regulator (LVR) with high electromagnetic immunity (EMI) was designed by taking voltage reference generated by temperature independent current and EMI feedback control strategy. The proposed circuit was implemented using a HV-BCD technology for vehicle applications. Simulation results show the regulator can supply 5V output voltage with maximum 100mA current and has good transient response performance. EMI test according Direct Power Injection (DPI) method depicts that less than 200mV DC drift generated @10 Vpp noise injection.
