FAQs

What is LR8K4-G?

The LR8K4-G is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. It is designed to provide a stable output voltage with low dropout voltage, making it ideal for applications where a clean and stable power supply is required.

How Does LR8K4-G Work?

The LR8K4-G works by regulating the input voltage to provide a constant output voltage regardless of variations in the input voltage or load conditions. It utilizes a feedback mechanism to adjust the output voltage, maintaining stability and accuracy even with fluctuations in input voltage and load current.

How Many Pins does LR8K4-G have and What are the Functions of the Pinout Configuration?

The LR8K4-G is available in various package options, such as SOT-223 and DPAK, which typically have three pins. The pinout configuration includes:

Input (VIN): Pin for connecting the input voltage.
Output (VOUT): Pin for accessing the regulated output voltage.
Ground (GND): Pin connected to the ground reference.

What are the Pros and Cons of LR8K4-G?

Pros:

Low Dropout Voltage: Provides a stable output even when the input voltage is close to the output voltage.
High PSRR (Power Supply Rejection Ratio): Filters out noise from the input supply, ensuring a clean output.
Thermal Shutdown Protection: Protects the regulator from overheating under high load conditions.
Short Circuit Protection: Safeguards the regulator and connected components in case of a short circuit.

Cons:

Heat Dissipation: May require a heat sink for better thermal management, especially at high load currents.
Quiescent Current: Consumes a small amount of current even when the load is minimal, affecting overall efficiency.

Are There Any Equivalents/Alternatives to LR8K4-G for Recommendation?

The LM2940 from Texas Instruments is a comparable LDO regulator with similar features.
Alternatives to the LR8K4-G include the ADP3336 from Analog Devices and the XC6206 from Torex Semiconductor.
