FAQs

What is LP38798SD-ADJ/NOPB?

The LP38798SD-ADJ/NOPB is an adjustable output voltage, ultra-low dropout linear regulator manufactured by Texas Instruments. It is designed to provide a stable and accurate voltage output for various applications, including powering microcontrollers, FPGAs, and other sensitive electronic components.

How Does LP38798SD-ADJ/NOPB Work?

The LP38798SD-ADJ/NOPB operates as a linear regulator that accepts an input voltage and provides a regulated output voltage. It utilizes a feedback mechanism to adjust the internal pass device to maintain a constant output voltage regardless of changes in the input voltage or load conditions. This ensures a stable power supply for the connected components.

How Many Pins does LP38798SD-ADJ/NOPB have and What are the Functions of the Pinout Configuration?

The LP38798SD-ADJ/NOPB comes in a 12-pin WSON (Wide Small Outline No-Lead) package. The pinout configuration includes:

IN: Input voltage pin.
EN: Enable pin for turning the regulator on/off.
VOS: Output voltage sense pin.
ADJ: Adjust pin for setting the output voltage.
NC (No Connect): Pins that are not connected.
GND: Ground pins.
OUT: Regulated output voltage pin.

What are the Pros and Cons of LP38798SD-ADJ/NOPB?

Pros:

Ultra-Low Dropout: Works with very low voltage differentials, suitable for low-power applications.
Adjustable Output: Offers flexibility in setting the output voltage to meet specific requirements.
Low Noise: Provides a clean and stable output voltage for sensitive circuits.
Thermal Protection: Includes built-in thermal shutdown protection for device safety.
Small Package: The WSON package is compact, saving board space in designs.

Cons:

Cost: Linear regulators may have higher power dissipation compared to switching regulators.
Efficiency: May not be as efficient as switching regulators, especially at high input-output differentials.
Heat Dissipation: Generates heat due to the linear regulation process, which may require heat sinking in some applications.

Are There Any Equivalents/Alternatives to LP38798SD-ADJ/NOPB for Recommendation?

The LM2937 from Texas Instruments is a similar adjustable linear regulator with low dropout voltage.
Alternatives to the LP38798SD-ADJ/NOPB include the LT3080 from Linear Technology and the MAX1693 from Maxim Integrated.
