Abstract
A voltage stabilization circuit includes a first sub-circuit. The first sub-circuit includes a first voltage stabilizing element; a first switching element; and a second switching element. For the first voltage stabilizing element, the first terminal is electrically connected to a first node, and the second terminal is grounded. For the first switching element, the first terminal is electrically connected to the first node, and the second terminal is electrically connected to a voltage stabilizing target. For the second switching element, the first terminal is electrically connected to the control terminal of the first switching element, and the control terminal is electrically connected to the first node. When the first voltage stabilizing element is in a first operating state, the second switching element is turned on, and the first switching element is turned off.
