The 5pcs L7812CV 12V voltage regulator 1.5A TO-220 is an essential component for anyone looking for a stable and reliable power supply in their electronics projects. This linear regulator provides a fixed +12V DC output with a maximum current of 1.5A, from an input voltage ranging between 14V and 35V DC.
This regulator comes in a TO-220 package, which makes mounting and heat dissipation easier, allowing safe and robust use in a variety of applications. It also includes thermal protection and internal current limiting, which helps prevent damage from overheating or overcurrent, increasing the device's durability and safety.
Main features:
- Fixed 12V output with a ±2% tolerance, ensuring a stable voltage for your circuits.
- Maximum output current of 1.5A, ideal for powering devices that require moderate power.
- Permitted input voltage between 14V and 35V, offering flexibility in the power supply.
- TO-220 package that makes installation easier and improves thermal dissipation.
- Thermal protection and current limiting for greater safety and durability.
- No capacitors are required for stability, although it is recommended to use at least 10µF capacitors at the input and output to reduce ripple.
Typical uses:
- Power supply for electronic circuits that need a constant 12V voltage.
- DIY electronics projects where a stable and safe power supply is required.
- Replacement or repair of power supplies in devices that operate at 12V.
- Applications in embedded systems, automation and robotics.

Customer Questions & Answers
What advantages does the L7812CV offer compared with using adjustable or switching regulators to obtain 12 V?
The L7812CV provides a fixed 12 V output with high stability and low noise, making it suitable for applications sensitive to voltage fluctuations. Unlike adjustable regulators, it does not require additional components to set the voltage, which simplifies the design and reduces the risk of errors. Compared with switching regulators, the L7812CV does not introduce switching noise, although it is less energy-efficient and generates more heat if the difference between input and output is large.
What are the operating limits in current and temperature for the L7812CV according to its specification?
The maximum output current is 1.5 A, provided a suitable heatsink is used; without a heatsink, the supported current may drop to below 1 A, depending on thermal dissipation. The operating temperature range is 0°C to +125°C, but it is recommended not to exceed 100°C at the case to ensure service life.
What types of supply and loads are compatible with this regulator? Does it require any specific input conditions?
It is compatible with any DC supply whose voltage is between 14 V and 35 V. It is recommended that the supply provides at least 2 V above the output voltage to maintain regulation (typical dropout: 2 V @ 1 A). It can power loads of up to 1.5 A, but for inductive loads or high inrush loads it is advisable to add capacitors (≥10 µF) at the input and output to filter ripple and prevent oscillation.
What protection mechanisms does the L7812CV include? Does it comply with any electrical safety standard?
The L7812CV includes internal current limiting and thermal shutdown protection in the event of overheating. It is designed to common international standards for components used in the electronics industry, but it does not have its own CE or UL certification; use in finished products may require additional evaluation of electromagnetic compatibility and electrical safety according to local regulations.
What is the L7812CV 12V voltage regulator used for?
The L7812CV is used to obtain a fixed and stable 12V DC output from a higher input voltage, protecting electronic circuits and ensuring a constant power supply.
What is the maximum current this regulator can deliver?
This regulator can deliver a maximum current of 1.5A as long as it is used with an appropriate heat sink.
Do I need to use capacitors with this regulator?
It is not strictly necessary, but it is recommended to use capacitors of at least 10µF at the input and output to remove noise and ripple from the power supply.
What package does the L7812CV have?
The L7812CV comes in a TO-220 package, which makes mounting easier and improves thermal dissipation.
Where can I buy the L7812CV 12V 1.5A TO-220 voltage regulator?
You can buy it from specialist electronics component stores such as Satkit, where they offer this pack of 5 units.
