LM317LZ/NOPB Information

Description

The LM317LZ/NOPB is a versatile linear voltage regulator from Texas Instruments. It allows for adjustable output voltages between 1.2V and 37V, making it suitable for various applications like power supplies, LED drivers, and battery chargers. Its robust design ensures high reliability with low failure rates, and it operates within an extended temperature range (-40°C to 125°C).

Features

The LM317LZ/NOPB features a compact design for easy integration, wide operating temperature range (-40°C to 125°C), short circuit protection for safety, adjustable output voltage from 1.2V to 37V, high accuracy regulation, robust fault tolerance, user-friendly interface with adjustable output, and superior thermal performance with low noise operation.

Package

The LM317LZ/NOPB has a TO-92 (LP)-3 package, which is a popular pin configuration for integrated circuits.

Pinout

The LM317LZ/NOPB is a three-pin voltage regulator, commonly known as TO-92 package. The pin count is three:


  • Pin 1 (Vin)
  • ): Input voltage terminal. Connects to the power source.

  • Pin 2 (Adjust)
  • ): Adjustability control for setting output voltage. It typically includes a variable resistor.

  • Pin 3 (Out)
  • ): Output voltage terminal. The voltage at this pin can be adjusted by controlling Pin 2.

Remember to connect the ground pins of both input and output sides when using LM317LZ/NOPB.

Manufacturer

The LM317LZ/NOPB is manufactured by Texas Instruments (TI), a multinational technology company known for its innovation in semiconductors, embedded systems, and software tools. TI's focus on quality and reliability make them a trusted partner in the electronic industry.

Applications

The LM317LZ/NOPB is widely used in applications like power supplies, voltage regulation, battery charging, and LED driving due to its adjustable output voltage and high regulation capabilities.

Equivalent

The LM317LZ/NOPB is a voltage regulator, but equivalent products include LM2940, LM318, and MC3406
These also offer adjustable output voltage for similar applications.
