概述
Description
The LM1084ISX-5.0 is a low dropout (LDO) linear voltage regulator designed to provide a fixed output voltage of 5.0 volts with a maximum output current of 5A. It features a dropout voltage of approximately 1.5V at full load, making it suitable for applications where maintaining regulation with a small differential between input and output voltage is critical.
This device comes in a surface-mount TO-263 package, making it suitable for designs with limited board space. It includes features such as current limiting and thermal protection to prevent damage under fault conditions. The LM1084ISX-5.0 is commonly used in applications requiring high-efficiency, fixed 5V supply, such as powering microprocessors, digital circuits, and other sensitive electronics.
The regulator requires a small number of external components, typically a pair of capacitors for input and output stability, which simplifies the design and implementation process. The LM1084 series is known for its low noise and accurate output, contributing to its reliability in powering precision electronics.

Package
The LM1084ISX-5.0 is a voltage regulator that typically comes in a TO-263 package. The TO-263, also known as the D2PAK, is a surface-mount package type used for high-power devices, offering good thermal performance and compactness, making it suitable for applications requiring efficient heat dissipation.
Pinout
The LM1084ISX-5.0 is a low-dropout (LDO) linear voltage regulator. It comes in a 3-pin TO-263 package. The pin count and functions are as follows:
1. Input (VIN): This pin receives the input voltage. The LM1084ISX-5.0 can handle an input voltage range greater than the desired output voltage to maintain regulation.
2. Output (VOUT): This pin provides a regulated output voltage of 5.0V. It maintains this voltage as long as the input voltage is sufficiently higher than the 5.0V output.
3. Ground (GND): This pin is connected to the ground of the circuit. It serves as a reference point for the input and output voltages and is essential for the operation of the regulator.
The LM1084ISX-5.0 is used in applications requiring a stable 5V output from a higher input voltage, with a maximum output current of up to 5A.
