The disclosure provides a low dropout linear regulator circuit and a memory, the circuit comprising: a first transistor, a second transistor and a feedback control circuit; the gate dielectric layer thickness of the first transistor is less than a preset threshold; the first end of the first transistor and the second end of the second transistor are connected to receive a power supply voltage; the second end of the first transistor and the first end of the second transistor are connected to output a target voltage; the control end of the second transistor receives a power-on control signal, and the second transistor is used to output the target voltage during the power-on process; the feedback control circuit is connected with the control end of the first transistor, the feedback control circuit is used to receive the power-on control signal, control the first transistor to be disconnected during the power-on process, and control the first transistor to output the target voltage after the power-on is completed; wherein the power-on control signal is in an enabled state during the power-on process, and is in a disabled state during the remaining period. The disclosure can reduce the circuit area, avoid overvoltage and simplify the timing.

The application belongs to the technical field of battery preheating, and particularly relates to a fast-response in-situ temperature control binder as well as a preparation method and application thereof. The application proposes a new binder, which uses hyperbranched polymers carrying a large number of charges to load fast-response particles through electrostatic interaction and redox reaction, and designs an external miniature heating device cooperating with the fast-response binder, so that the impedance of the battery is not increased, and the effect of non-contact fast heating of the battery interior can be achieved only by using the binder when assembling the battery and cooperating with the external device. The battery can be raised from minus 60 degrees Celsius to room temperature in 5 seconds, and the battery in hibernation due to low temperature can be quickly woken up to discharge and work again. The application has great significance for the field of battery low-temperature preheating, and provides a brand-new heating strategy, which creates an unprecedented new idea for the use of the battery at low temperature.

This utility model relates to the technical field of integrated cord lamps, specifically a single-sided integrated cord lamp. The utility model includes an energizing mechanism, which comprises a mounting plate on which an electric cylinder is fixedly mounted. The electric cylinder is vertically mounted and drives an energizing plate, the lower end of which has an inclined edge. This utility model uses the electric cylinder to drive the energizing plate downwards, causing the inclined edge at the lower end of the energizing plate to contact the copper wire, thereby quickly energizing the copper wire for LED detection. The energizing plate is small in size, can easily contact and energize different copper wires, is less prone to short circuits, and has a good energizing effect.
