Claim:
1. A voltage regulator configured to generate an internal source voltage on the basis of a source voltage in an operational mode is selected from either an active mode or a standby mode, said voltage regulator comprising: a drive voltage generating part configured to generate a drive voltage and then apply said drive voltage to a drive line; an output transistor configured to output a voltage corresponding to a voltage value of said drive line as said internal source voltage; and a compulsory drive circuit including a capacitor element configured to receive said source voltage at one end, a first switching element configured to receive a ground voltage and apply said ground voltage to the other end of said capacitor element by being set in an ON state over a period in which the selected operational mode is said standby mode, and a second switching element that connects said other end of said capacitor element to said drive line only for a predetermined period in an ON state when said operational mode transitions from said standby mode to said active mode.
