Hearing instrument configured for wireless communication in bursts and a method of supplying power to such

A hearing instrument configured to receive power from an energy source, the energy having an output voltage, the hearing instrument comprising:

• an analog-to-digital converter for conversion of an input audio signal to a digital input signal;
• a digital signal processor for processing the digital input signal into a processed signal;
• an audio amplifier for amplifying the processed signal;
• a communication unit for wireless data communication between the hearing instrument and another device;
• and
• a first stabilizing circuit configured to provide a stabilized supply voltage to a sub-circuit at least during a transient drop in the output voltage of the energy source, wherein the sub-circuit comprises one or more of the analog-to-digital converter, the digital signal processor, and the audio amplifier;
• wherein the first stabilizing circuit comprises an energy storing element and a rectifying element, wherein the energy storing element is configured to supply power to the first sub-circuit, and the rectifying element is configured to prevent the energy storing element from supplying power to the communication unit.
