摘要
An adaptive low-dropout regulator (LDO) having a wide voltage endurance range includes a power supply voltage tracker (P1), a voltage-current converter (101), an error amplifier (201), a current mirror circuit (102), and a dynamic voltage divider (103). One end of the power supply voltage tracker (P1) is connected to a Vdd, the other end thereof is connected to the voltage-current converter (101) connected to an input end of the current mirror circuit (102), and an output end of the current mirror circuit (102) is connected to sources of two input field effect transistors (N3, N4) in the error amplifier (201). Sources of two load field effect transistors (P2, P3) in the error amplifier (201) are connected to the Vdd. Dynamic voltage dividers (103A, 103B) are connected respectively between each of the input field effect transistors (N3, N4) and the corresponding load field effect transistors (P2, P3).
