FAQs
What is L7820CV?
The L7820CV is a fixed output linear voltage regulator integrated circuit (IC) manufactured by STMicroelectronics. It is designed to provide a regulated output voltage of +20V with a maximum output current of 1.5A. The device is commonly used in various electronic circuits to ensure a stable and constant voltage supply.
How Does L7820CV Work?
The L7820CV operates by taking an unregulated input voltage and regulating it to a fixed +20V output voltage. The internal circuitry of the IC adjusts the output voltage by controlling the conduction of internal pass transistors, thereby maintaining a stable voltage regardless of input variations. This regulated output voltage can then be used to power other components in the circuit.
How Many Pins does L7820CV have and What are the Functions of the Pinout Configuration?
The L7820CV comes in a TO-220 package with 3 pins. The pinout configuration includes:
- Input (VIN): Unregulated input voltage pin.
- Output (+20V): Regulated +20V output voltage pin.
- Common (GND): Ground connection pin.
What are the Pros and Cons of L7820CV?
Pros:
- Regulated Output: Provides a stable +20V output voltage for powering other components.
- High Output Current: Capable of delivering up to 1.5A of current for moderate power applications.
- Thermal Protection: Includes built-in thermal shutdown protection for safe operation.
- Simple Design: Easy to use and suitable for basic voltage regulation needs.
- Cost-Effective: Offers a cost-effective solution for voltage regulation requirements.
Cons:
- Fixed Output Voltage: Limited to a fixed +20V output voltage, which may not suit all applications.
- Heat Dissipation: May require a heat sink for proper heat dissipation, especially at higher currents.
- Wastage: Linear regulators dissipate excess power as heat, resulting in lower efficiency compared to switching regulators.
Are There Any Equivalents/Alternatives to L7820CV for Recommendation?
- The LM340T-20 from Texas Instruments is a similar +20V linear regulator with comparable specifications.
- Alternatives to the L7820CV include the UA78M20CKCSE3 from Texas Instruments and the MC7820CT from ON Semiconductor.
