Description

The LT1083CP#PBF is a low dropout (LDO) linear voltage regulator designed for applications requiring high current and low dropout voltage. It belongs to the LT1083 series, which includes other variants capable of handling different current levels. The "#PBF" suffix indicates that the component is lead-free and complies with RoHS standards, making it suitable for environmentally friendly designs.
The LT1083CP can deliver up to 7.5A of output current with a dropout voltage of about 1.5V at maximum load, making it ideal for systems requiring high efficiency from the input to output voltage conversion. The device features protection mechanisms such as current limiting and thermal shutdown, ensuring reliable operation under various conditions. Additionally, the LT1083CP provides adjustable output voltage, allowing for flexibility according to the specific application requirements.
Typically housed in a TO-220 package, the LT1083CP#PBF is widely used in power supply designs for computers, networking equipment, and other electronics where efficient voltage regulation is crucial.

Features

The LT1083CP#PBF is a low dropout (LDO) linear voltage regulator designed by Analog Devices (formerly Linear Technology). Key features of the LT1083CP#PBF include:
1. Output Current: Capable of providing up to 7.5A of output current.
2. Low Dropout Voltage: Features a dropout voltage of around 1V at maximum output current, which means it requires only a small difference between the input and output voltage to maintain regulation.
3. Adjustable Output Voltage: The output voltage can be adjusted with an external resistor network, offering versatility for different applications.
4. Thermal Performance: Includes thermal overload protection, ensuring the device shuts down if it overheats, which enhances reliability.
5. Safe Operating Area Protection: Designed with safe area protection to prevent excessive power dissipation.
6. Package Type: Available in TO-3P package, which helps with heat dissipation.
7. High Stability and Low Noise: Provides a stable output with low noise, suitable for sensitive electronic applications.
These features make the LT1083CP#PBF ideal for applications requiring high current and low dropout voltage, such as power management in industrial and consumer electronics.

Package

The LT1083CP#PBF is a linear voltage regulator in a TO-220 package. This package type features three leads and is commonly used for through-hole mounting, providing efficient heat dissipation with its metal tab, which can be attached to a heat sink if necessary.

Pinout

The LT1083CP#PBF is a positive linear voltage regulator from Analog Devices. It typically comes in a TO-220 package with a pin count of 3. The function of each pin is as follows:
1. Input (IN): This pin receives the unregulated input voltage. It should be connected to the positive side of the input power supply.
2. Output (OUT): This pin provides the regulated output voltage. Connect this pin to the load that requires a stable voltage.
3. Adjustment (ADJ): This pin allows for the adjustment of the output voltage. By connecting a resistor divider between the output and the ground, you can set the desired output voltage.
The LT1083CP#PBF is designed to provide a stable output voltage with high current capability and low dropout voltage, making it suitable for various power supply applications.
