Description

The LM1085ISX-ADJ is a low dropout (LDO) voltage regulator produced by Texas Instruments. It is designed to provide a stable output voltage that is adjustable using an external resistor divider. The device can deliver up to 3A of output current with a dropout voltage of approximately 1.5V at full load.
Key features of the LM1085ISX-ADJ include high accuracy, thermal protection, and current limiting to prevent device damage under fault conditions. It operates over a wide input voltage range and is known for its ease of use in various applications requiring a regulated power supply. The adjustable output feature makes it versatile for multiple voltage requirements in electronic circuits.
The LM1085ISX-ADJ comes in a TO-263 surface-mount package, making it suitable for space-constrained applications. It is widely used in consumer electronics, industrial, and communication equipment where reliability and efficiency are necessary.

Features

The LM1085ISX-ADJ is a low dropout (LDO) voltage regulator from Texas Instruments designed to provide a fixed or adjustable output voltage with a high output current capability of up to 3A. Key features include:
1. Adjustable Output Voltage: The device allows for output voltage adjustments, typically ranging from 1.25V up to 29V, depending on the input voltage and external resistors used.
2. Low Dropout Voltage: It features a low dropout voltage of approximately 1.3V at maximum output current, making it suitable for applications with low input-output voltage differentials.
3. Thermal Protection: The LM1085ISX-ADJ is equipped with internal thermal overload protection, ensuring the device is protected from excessive temperature conditions.
4. Current Limiting: It includes current limiting to protect against overload conditions.
5. High Accuracy: Offers high output voltage accuracy, typically within ±1%, ensuring reliable performance.
6. Package Options: Available in surface-mount TO-263 and TO-220 packages to accommodate different application needs.
These features make the LM1085ISX-ADJ ideal for use in applications like power supplies for microprocessors, high-efficiency linear regulators, and post-regulation for switching supplies.

Package

The LM1085ISX-ADJ is available in a TO-263 surface-mount package. This package type is designed for efficient thermal performance, suitable for applications requiring a compact footprint and effective heat dissipation.

Pinout

The LM1085ISX-ADJ is a low dropout linear regulator with an adjustable output. It typically comes in a TO-263 surface-mount package with three pins. The pin functions are as follows:
1. Pin 1 (Adjust/Feedback): This pin is used to set the output voltage by connecting it to the resistor divider network. The voltage at this pin adjusts the output to the desired level.
2. Pin 2 (Output): This is the output pin of the regulator where the regulated voltage is available. The load is connected to this pin.
3. Pin 3 (Input): This is the input pin for the unregulated voltage supply, which should be higher than the desired output voltage by the dropout voltage.
The LM1085ISX-ADJ can deliver an output current of up to 3A with a dropout voltage of around 1.5V, depending on the current. It is designed for applications requiring a stable and adjustable output voltage with high current capability.
