The output current of the 1.5V three-terminal regulator depends on its rated current and load resistance. Under normal circumstances, the rated current of the regulator refers to the maximum current that can provide a stable output voltage within its operating range. If the load resistance is small, the output current of the regulator will be close to its rated current. However, if the load resistance is large, the output current of the regulator tube will be reduced. Therefore, to determine the output current of the 1.5V three-terminal voltage regulator, it is necessary to consider its rated current and load resistance.
The stable working current is 15.5mA. The current is too large because the resistance value of the current limiting resistor is too small...
