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?
