FAQs
What is L4940V85?
The L4940V85 is a voltage regulator IC manufactured by STMicroelectronics. It is a low-dropout (LDO) regulator capable of delivering a fixed output voltage of 8.5V with high accuracy and low dropout voltage. This device is commonly used in various electronic applications to provide stable voltage regulation.
How Does L4940V85 Work?
The L4940V85 operates by accepting an input voltage typically higher than the desired output voltage and regulating it down to a constant 8.5V output. It maintains this output voltage even when the input voltage varies or when there are fluctuations in the load current. The LDO regulator ensures a stable and precise voltage supply to connected components.
How Many Pins does L4940V85 have and What are the Functions of the Pinout Configuration?
The L4940V85 comes in a TO-220 package with 3 pins. The pinout configuration includes:
- Input (VIN): Accepts the input voltage to be regulated.
- Ground (GND): Connects to the ground reference point.
- Output (VOUT): Provides the regulated output voltage of 8.5V.
What are the Pros and Cons of L4940V85?
Pros:
- Stable Output: Provides a stable output voltage of 8.5V.
- Low Dropout Voltage: Works with a low dropout voltage, suitable for low voltage applications.
- Thermal Shutdown Protection: Includes thermal shutdown protection to prevent overheating.
- Short Circuit Protection: Offers short circuit protection for added safety.
- Easy to Use: Simple 3-pin configuration for ease of installation and operation.
Cons:
- Heat Dissipation: May require a heat sink for better heat dissipation in high-power applications.
- Limited Voltage Options: Fixed output voltage of 8.5V may not be suitable for all applications that require variable voltages.
Are There Any Equivalents/Alternatives to L4940V85 for Recommendation?
- The LM340T-8.5 from Texas Instruments is a similar 8.5V fixed voltage regulator.
- Alternatives to the L4940V85 include the UA78M08CDCYR from Texas Instruments and the MC78M08CDTRKG from ON Semiconductor.
