Definitions

  • Patent Document 1 discloses a voltage regulation circuit having a low dropout voltage regulator and a current source.
  • the low dropout voltage regulator includes an output section coupled to the power supply input section of the load circuit and is configured to supply the power supply voltage to the load circuit.
  • the current source is coupled to the power input section of the load circuit and the output section of the low dropout voltage regulator, and supplies current to the load circuit so as to reduce the current supplied to the load circuit by the low dropout voltage regulator.
  • the input circuit unit applies a voltage corresponding to the combination of the first states at the plurality of output terminals to the first terminal.
  • the transistor is energized when at least one of the output terminals is in the first state.
  • the switch is turned on when the transistor is energized.
  • the element unit defines the output voltage applied to the second conductive path to a voltage corresponding to the voltage applied to the first terminal.
  • the voltage regulator which is an example of the present disclosure, is (1)
  • the control unit operates so as to switch each state of the plurality of output terminals to either the first state or the second state.
  • the input circuit unit applies a voltage corresponding to the combination of the first states at the plurality of output terminals to the first terminal.
  • the transistor is in the energized state when at least one of the output terminals is in the first state, and the switch is in the on state when the transistor is in the energized state.
  • the element unit sets the output voltage applied to the second conductive path to a voltage corresponding to the voltage applied to the first terminal.
  • One end of the resistor 33 is connected to the other end of the resistor 37 and the base of the transistor 41.
  • One end of the resistor 33, the other end of the resistor 37, and the base of the transistor 41 have the same potential.
  • One end of the resistor 35 is connected to the other end of the resistor 33 and the other end of the resistor 39.
  • One end of the resistor 35, the other end of the resistor 33, and the other end of the resistor 39 have the same potential.
  • the other end of the resistor 37 and the other end of the resistor 39 are connected to each of the inter-element conductive paths 93 and 94 in the series component 31.
  • the other end of the resistor 35 is connected to the ground and has a ground potential.
  • the control unit 20 operates so as to switch each state of the ports P1 and P2 to either the first state or the second state, thereby switching a plurality of types of Vb to the transistor 41. It can be applied to the base and the output voltage Vout can be changed accordingly. In this way, one voltage regulator 10 can output output voltages of a plurality of different sizes.
  • the voltage regulator 10 can gradually switch the voltage applied to the base of the transistor 41 by controlling the plurality of ports P1 and P2 by the control unit 20, and such a configuration is defined as "a plurality of resistors 33, 35 and It can be realized by a simple configuration mainly composed of a plurality of resistors 37 and 39. Moreover, since the control unit 20 only needs to switch the plurality of ports P1 and P2 to the high level voltage or the low level voltage, the control of the control unit 20 is also simplified.
