ABSTRACT:
The invention relates to a voltage regulating circuit arrangement for converting a first voltage (VEXT) applied to an input of said voltage regulating circuit arrangement into a second voltage (VBLH) that may be tapped at an output of said voltage regulating circuit arrangement, wherein, when said first voltage (VEXT) falls below a threshold value (VEXT_THRESHOLD), the first voltage (VEXT) applied to the input of said voltage regulating circuit arrangement is connected through to said output of said voltage regulating circuit arrangement.
