Title:
ELECTRONIC EQUIPMENT
Document Type and Number:
Japanese Patent JP2003167636
Kind Code:
A
Abstract:

To prevent the reset of electronic equipment due to a rush current at turning ON a voltage regulator when power is supplied.

At turning ON a voltage regulator REG 3 for supplying a constant voltage V3 to a display circuit 17, the REG 3 is turned ON/OFF in a short cycle, and then normally turned ON under the control of a control circuit 14. Thus, it is possible to reduce the rush current to a capacitor C3 when the power is supplied, and to suppress the deterioration of a power supply voltage VB due to the rush current, and to prevent a reset signal from being outputted from a voltage detecting circuit 15.
