概述
Description
The LM1084IT-ADJ/NOPB is a low dropout (LDO) linear voltage regulator designed to provide a stable output voltage with a maximum output current of 5A. It is part of the LM1084 series produced by Texas Instruments. The "ADJ" indicates that this version is adjustable, allowing users to set the output voltage to a desired level using an external resistor divider. The device features a dropout voltage of approximately 1.5V at full load, which makes it suitable for applications requiring efficient voltage regulation close to the input voltage level.
The LM1084IT-ADJ/NOPB is known for its robust performance in thermal and overload conditions, integrating thermal shutdown and current limit protection. It is typically used in applications such as post-regulation for switching supplies, high-efficiency linear regulators, and battery chargers. Housed in a TO-220 package, it offers ease of mounting and handling. The component is characterized by low quiescent current and high precision output regulation, making it a reliable choice for maintaining stable voltage in various electronic devices and systems.

Package
The LM1084IT-ADJ/NOPB is a voltage regulator with an adjustable output. It comes in a TO-220 package type, which is a through-hole package commonly used for power components due to its ability to handle higher power dissipation.
Pinout
The LM1084IT-ADJ/NOPB is a low-dropout (LDO) linear voltage regulator. It typically comes in a TO-220 package and has three pins.
1. Pin 1 (Adjust/Feedback): This pin is used to set the output voltage. It connects to the resistor divider network to adjust the output voltage based on the required application.
2. Pin 2 (Output): This pin provides the regulated output voltage. The output voltage can be adjusted using external resistors connected to the Adjust pin and the ground.
3. Pin 3 (Input): This pin receives the input voltage, which should be higher than the desired output voltage by a small margin to maintain regulation.
The LM1084IT-ADJ/NOPB is capable of delivering up to 5A of output current with a dropout voltage around 1.5V, making it suitable for high-current applications where a low dropout voltage is essential.
