The utility model relates to the technical field of low-dropout linear
voltage regulators, and discloses a low-dropout linear
voltage regulator which comprises a circuit board, a sliding groove is fixedly connected to the top face of the circuit board, two sets of sliding blocks are connected into the sliding groove in a sliding mode, one side of each sliding block is fixedly connected with a shifting piece, the bottom of each shifting piece is connected with a sliding
assembly in a sliding mode, and the sliding
assembly is fixedly connected with the top face of the circuit board. The bottom surface of the circuit board is fixedly connected with two groups of fixing sheets, and a
voltage stabilizer is inserted into the top surface of the circuit board. According to the low-dropout linear
voltage regulator, through the arrangement of the sliding
assembly and the inserting column, when the
voltage regulator needs to be installed, the inserting column fixed to the bottom face of the
voltage regulator is aligned with the inserting opening for inserting, the effect of convenient installation can be achieved, and when the voltage
regulator needs to be disassembled and replaced, the two sets of poking pieces are pinched to slide on the supporting column, and the two sets of poking pieces can be conveniently disassembled and replaced. Therefore, the effect of safely and conveniently pulling out the voltage stabilizer is achieved, and the convenience of mounting and dismounting the voltage stabilizer is improved.
