    Abstract: Dispositif de régulation à faible chute de tension, comprenant un amplificateur d'erreur (AE) et un étage de puissance (ETP) ayant une borne de sortie (BS) rebouclée sur l'amplificateur d'erreur (AE) et apte à délivrer un courant de sortie dans une charge (RL, CL). Le dispositif comprend plusieurs entrées principales d'alimentation (EALPi) destinées à potentiellement recevoir respectivement plusieurs tensions d'alimentation différentes, en ce que l'étage de puissance (ETP) comprend plusieurs chemins de conduction (PTHi) respectivement connectés entre lesdites entrées principales d'alimentation et ladite borne de sortie, individuellement sélectionnables et comportant chacun un transistor de sortie (MPgi), en ce qu'il comprend en outre un circuit de sélection (CSL) connecté auxdites entrées principales d'alimentation et configuré pour sélectionner l'un des chemins de conduction (PTHi) en fonction d'un critère de sélection, et en ce que l'amplificateur d'erreur (AE) comporte un étage de sortie (ETS) configuré pour piloter sélectivement le transistor de sortie (MPgi) du chemin de conduction sélectionné.

    Abstract: A circuit can be used for reading out a light sensor. The circuit includes an operational amplifier. A first capacitor has a first electrode coupled to an inverting input of the operational amplifier and a second electrode coupled to a non-inverting output of the operational amplifier. A compensation circuit is coupled between the operational amplifier and the first capacitor. A preset circuit has an input coupled to a first voltage node and an output coupled to the first capacitor. The first voltage node configured to carry a first voltage equal to a preset voltage multiplied by a coefficient.
