POWER MANAGEMENT SYSTEM FOR A HEARING AID

摘要

An apparatus for a hearing device includes a first voltage regulator with an output terminal; a first voltage reference; a second voltage regulator with an output terminal; a switching element; and a decoupling element; wherein the switching element and the decoupling element are operatively between the first voltage reference and the first voltage regulator; wherein the output terminal of the first voltage regulator shares a same electrical node as the output terminal of the second voltage regulator; and wherein the first voltage regulator is configured to provide a first output voltage in response to applied battery power, the second voltage regulator is configured to provide a second output voltage if a certain condition is fulfilled, and the switching element is configured to disconnect the first voltage reference from the decoupling element if the condition is fulfilled.
