FAQs
What is LP3964EMP-ADJ?
The LP3964EMP-ADJ is an adjustable, high-current, low dropout voltage regulator manufactured by Texas Instruments. It is designed to provide a stable and precise output voltage for various electronic systems, including industrial equipment, automotive applications, and telecommunications devices.
How Does LP3964EMP-ADJ Work?
The LP3964EMP-ADJ regulates the output voltage by comparing the reference voltage with a feedback voltage generated from the output. It adjusts the pass element to maintain the desired output voltage regardless of variations in input voltage and load conditions. The low dropout voltage feature enables efficient regulation even when the input voltage is close to the output voltage.
How Many Pins does LP3964EMP-ADJ have and What are the Functions of the Pinout Configuration?
The LP3964EMP-ADJ is available in a 20-lead HTSSOP (PowerPAD™) package. The pinout configuration includes:
- VIN: Input voltage pin.
- VOUT: Output voltage pin.
- ADJ: Adjustable voltage pin.
- GND: Ground pin.
- ByPass or Compensation Pin: Capacitor connection pin for stability.
- Enable: Enable pin for On/Off control.
