Abstract:
A high current drive bandgap based voltage regulator for providing a reference voltage at a an output voltage at a designed output voltage value. The high current drive bandgap based voltage regulator includes a high current drive output transistor, a feedback network, an output terminal and an operational amplifier. The feedback network is coupled between the output of the transistor and the input of the transistor. The operational amplifier is in the feedback network and has at least two operational amplifier input terminals and an operational amplifier output terminal. The operational amplifier output terminal is coupled to the transistor input terminal, and the operational input terminals are coupled to the transistor output terminal. The output terminal of the high current drive bandgap based voltage regulator is coupled to the output of the high current drive transistor. The high current drive bandgap based voltage regulator is operable to provide a current of at least 100 μA to the output terminal while maintaining the output voltage at the output terminal at a value substantially equal to the designed output voltage value.
