Abstract:

A low leakage current power regulator is disclosed. The low leakage current power regulator comprises a starter, a leakage holder, a discharger and a linear regulator. The regulator provides a low current to the chip when a low current consumption part is active and provides a high current to the chip when a high current consumption logic is active. The power regulating technique in accordance with the present invention serves to reduce the standby current to a negligible level, keep the device alert to external instructions and provide a large enough working current (amps level).
