Frequently Asked Questions
What is the output voltage and maximum output current of the L7805ACP?
The L7805ACP provides a fixed 5-V regulated output voltage with a maximum continuous output current of 1.5 A. It features a maximum line regulation of 0.05%, ensuring the output remains stable across a wide range of input voltages from 7.5 V to 18 V (absolute maximum 35 V).
What is the dropout voltage of the L7805ACP?
The L7805ACP has a nominal dropout voltage of 2 V at rated output current. This means the input voltage must be at least 7 V (5 V output + 2 V dropout) to maintain regulation. For applications near the input voltage minimum of 7.5 V, this dropout specification is an important design consideration to ensure reliable regulation.
What package does the L7805ACP use and is it suitable for high-power applications?
The L7805ACP uses a through-hole TO-220 style power package with JESD-30 designation R-PSFM-T3, which provides excellent heat dissipation through its metal tab. This package can be bolted to an external heatsink to handle sustained 1.5-A loads, making it well suited for benchtop supplies, industrial control boards, and other applications requiring robust thermal management.
Is the L7805ACP still in production and easy to source?
The L7805ACP has been in production since 1980, making it one of the most widely available linear regulators in the industry. However, note that the YTEOL (Years to End of Life) indicator is 0, which may signal end-of-life or limited production status. It is advisable to check current stock levels and consider alternative devices for new designs requiring long-term supply continuity.
What are common applications for the STMicroelectronics L7805ACP?
Common applications include regulated 5-V power supplies for microcontrollers and TTL logic circuits, bias supply for op-amps and analog sensor circuits, industrial control panels, test and measurement equipment, and benchtop laboratory power supplies. Its robust TO-220 package, 1.5-A rating, and simple two-external-capacitor design make it a go-to solution for straightforward power regulation needs.
