Publication number: 20240126315Abstract: The present disclosure relates to a device having a supply input receiving a supply voltage, a switched-mode power supply comprising an output at which is generated a supply voltage, and a voltage linear regulator supplying a load, the regulator receiving the supply voltages, the regulator including two transistors coupled between the supply input, respectively the output of the supply, and an output node of the regulator. When the current drawn by the load is below a threshold, an output current delivered to the load is equal to a current flowing through the transistor, so that, when the current drawn by the load is above the threshold, the output current is equal to a current flowing through the transistor plus a current flowing through the transistor.Type: ApplicationFiled: September 6, 2023Publication date: April 18, 2024Inventor: Alexandre Pons
