shop/ circuitrocks/ lm7805 / l7805cv 5v voltage regulator

The LM7805/L7805CV is a three-terminal positive linear voltage regulator designed to provide a stable 5 V DC output for electronic circuits and embedded systems. It can accept an input voltage of up to 35 V and provide an output current of up to 1.5 A, depending on operating and thermal conditions.

The regulator uses a standard TO-220 package, making it easy to install on PCBs, breadboards, and other electronic prototypes. It also includes built-in protection features such as current limiting and thermal shutdown, helping protect the device from excessive current and overheating.

The LM7805/L7805CV is commonly used to supply regulated 5 V power to Arduino boards, sensors, microcontrollers, modules, and other low-voltage electronic components. When operating at higher current loads or with a large difference between input and output voltage, a suitable heatsink may be required to manage heat dissipation.

Key Features:

  • Fixed 5 V DC output
  • Maximum output current of 1.5 A
  • TO-220 3-pin package
  • Input voltage up to 35 V
  • Positive linear voltage regulation
  • Built-in current limiting
  • Thermal shutdown protection
  • Suitable for PCB and breadboard applications
  • Commonly used with Arduino, sensors, microcontrollers, and electronic modules

FAQ

Will this ship from Manila?

Yes — all stock ships from our Quezon City warehouse. Order before 4 PM weekdays for same-day cutoff via J&T or LBC.

Do you ship nationwide?

Yes. Metro Manila usually arrives next-day; provincial 1–3 working days.

Can I get this on a school PO or class order?

Yes — we accept Purchase Orders from accredited schools and universities. Contact us with your PO details and we'll process it.

Is this compatible with Arduino, ESP32, or Raspberry Pi?

Most parts work with common maker boards — check the description for specific pinout / voltage notes. If you're unsure, send us a message before ordering.

What's your return policy?

7-day inspection window for DOA units. Email proof of issue and we'll ship a replacement or refund. Used / installed parts are not returnable unless faulty.

Do you offer technical support?

Yes — questions land on our forum or via email, weekday or weekend. We've actually wired up most of what we sell.
