发明名称 POWER SUPPLY FOR A RTC
摘要 The invention relates to a linear regulator (1) comprising: - input means (2) configured to receive an input voltage, - output means (3) configured to deliver an output voltage, - a shunt element (4) coupled to said input means and said output means, and configured to be passed through by a current and to exhibit across its terminals a voltage drop independent of said current, - controllable by-pass means (5) coupled between said input means and said output means, and configured to have a first state for by-passing said shunt element and a second state for not by-passing said shunt element, and - control means (7) coupled to said input means and configured to place said by-pass means in their first state or in their second state depending on the value of said input voltage. The invention also relates to an electronic device comprising such a linear regulator.
