FAQs

What is ADP123AUJZ?

The ADP123AUJZ is a low-dropout (LDO) voltage regulator manufactured by Analog Devices. It is designed for applications requiring a stable and precise output voltage with low dropout voltage, making it suitable for powering sensitive electronic components.

How Does ADP123AUJZ Work?

The ADP123AUJZ works by taking an input voltage and regulating it to provide a constant output voltage. It maintains regulation by comparing the output voltage to a reference voltage and adjusting the internal circuitry to keep the output stable. The LDO design allows for minimal voltage drop between the input and output, making it efficient for various power supply applications.

How Many Pins does ADP123AUJZ have and What are the Functions of the Pinout Configuration?

The ADP123AUJZ is housed in a 5-lead TSOT (Thin Small Outline Transistor) package. The pinout configuration includes:

  • VOUT: Output voltage pin.
  • NC: No-connect pin.
  • VIN: Input voltage pin.
  • SGND: Sense ground pin for remote sensing.
  • PGND: Power ground pin.

What are the Pros and Cons of ADP123AUJZ?

Pros:

  • Precision: Provides a stable output voltage with low noise and high accuracy.
