FAQs
What is LD1084V33?
The LD1084V33 is a low dropout voltage regulator designed by STMicroelectronics. It is a 3.3V, 5A voltage regulator ideal for powering microcontrollers, DSPs, FPGAs, and other digital ICs that require a stable and regulated power supply.
How Does LD1084V33 Work?
The LD1084V33 works by taking an input voltage, which can be higher than the desired output voltage, and regulating it to a constant 3.3V output. It is a low dropout regulator, meaning it can maintain regulation with a small voltage differential between the input and output, making it suitable for applications where the input voltage may only be slightly higher than the output voltage.
How Many Pins does LD1084V33 have and What are the Functions of the Pinout Configuration?
The LD1084V33 is housed in a TO-220 package. The pinout configuration includes:
- Input (VIN): The input voltage is applied to this pin.
- Output (VOUT): The regulated 3.3V output voltage is available at this pin.
- Adjust (ADJ): This pin allows for an external resistor divider to set the output voltage, although in the case of LD1084V33, it is typically connected to ground to set the output to 3.3V.
- Ground (GND): The ground or common reference point for the regulator.
What are the Pros and Cons of LD1084V33?
Pros:
- High Current Capacity: Capable of delivering up to 5A of output current.
- Low Dropout Voltage: Can regulate the output voltage with a small differential between input and output.
- Thermal Regulation: Includes over-temperature protection and thermal shutdown features.
- Simple Application: The basic configuration with a few external components makes it easy to use.
- Cost-Effective: Provides a cost-effective solution for low dropout voltage regulation.
Cons:
- Heat Dissipation: May require a heat sink for high-power applications to manage thermal dissipation.
- External Components: Although minimal, some external components are required for stable operation.
Are There Any Equivalents/Alternatives to LD1084V33 for Recommendation?
Some equivalents to the LD1084V33 include the LM1084 from Texas Instruments and the L4940V5 from STMicroelectronics. Alternatives can also include adjustable low dropout regulators such as the LM317 or the LT1086 from Linear Technology.
