What is the full name of _l7805cv in the 5 of 57805cv?

The full name of the L7805CV is a series of three-terminal voltage regulator ICs. This component is widely used in electronic circuits for providing a stable 5V DC output. The image below shows a typical representation of the L7805CV.

The L7805CV is a positive voltage three-terminal regulator, where the "78" at the beginning indicates it's a positive voltage regulator, while "79" would be used for negative voltage regulators. The "05" in the name stands for an output voltage of 5 volts. Therefore, the L7805CV is a positive 5V three-terminal voltage stabilizer. It can be directly replaced by similar ICs such as 78L05, 78M05, or LT7805 in most applications. In general, the L7805CV provides an output voltage range of 4.75V to 5.25V, with a quiescent current between 4.2mA and 8mA. This makes it suitable for low to moderate power applications where a stable 5V supply is needed. Here are the basic parameters of the L7805CV:
Key features of the L7805CV include: - Maximum output current of up to 1.5A - No need for external compensation components - Built-in current limiting protection to prevent damage from short circuits - Thermal shutdown protection to avoid overheating and device failure - Power limitation circuit to protect the output driver transistor This IC is commonly found in power supplies, microcontroller circuits, and various embedded systems that require a reliable 5V DC source. Its robust design and ease of use make it a popular choice among engineers and hobbyists alike. Whether you're working on a simple project or a more complex system, the L7805CV offers a dependable solution for voltage regulation.
Dry Type Transformer
We adopt the advanced technology imported from Europe, patented technology, specialized software to optimize the design for dry type transformer. The core is made of cold-rolled grain-oriented silicon steel sheet which cut in step-lap by GEORG Germany TBA core cutting lines and laminated by the method of fifth-order step-by-step stacking technology, enabling the no-load performance of the core to improve greatly. The epoxy resin from American HUNTSMAN is adopted for the windings which casted in the vacuum resin casting machine imported from HEDRICH, Germany. The winding material ensures good permeability, no bubbles occur, which leads to minimum partial discharge. The HV and LV winding mate with each other tightly, which ensures solid strength of structure and capability to withstand short circuit and vibration. Under normal service condition, the service life of dry type transformer is 30 years. No crack will form on the surface of transformer winding due to temperature variation as long as the transformer runs under normal service condition.
