Abstract (en)
[origin: EP1197825A2] The device has first parts whose supply voltage is the same as the external voltage supply and second parts with a lower supply voltage derived from the first. The internal supply voltage is provided by an active potential divider with a first resistive potential divider between the supply voltage and reference potential, an impedance converter and a circuit for load-dependent control of the resistive potential divider tapping voltage. The device has first parts whose supply voltage is the same as the external voltage supply and second parts with a lower supply voltage derived from the first supply voltage. The internal supply voltage is provided by an active potential divider containing a first resistive potential divider (R1, R2) between the supply voltage connection (Pad) and a reference potential, an impedance converter (T1) and a circuit for load-dependent control of the divided voltage at the tapping (X) of the first resistive potential divider.
