Description

The LM337IMPX is a versatile, adjustable negative voltage regulator designed for a wide range of applications. It allows for the regulation of output voltages ranging from -1.2V to -37V with a current output capability of up to 1.5A, making it suitable for providing a stable power supply in various electronic circuits. The device is characterized by its ease of use, requiring only two external resistors to set the desired output voltage.
Manufactured by Texas Instruments, the LM337IMPX offers features like thermal overload protection, short-circuit current limiting, and safe-area compensation, which enhance its reliability and safety in operation. The device is available in a surface-mount package, which facilitates integration into circuit boards with space constraints. It is commonly used in applications such as power supplies, battery chargers, and any circuits needing a stable negative voltage supply. Its low dropout voltage and high ripple rejection further contribute to its efficiency and effectiveness in maintaining consistent performance even in challenging conditions.

Features

The LM337IMPX is a voltage regulator that provides adjustable negative output voltage, typically used in power supply applications. Key features include:
1. Adjustable Output Voltage: It allows output voltage adjustment from -1.25V to -37V, making it versatile for various applications.
2. Current Capability: The device can supply a current output of up to 1.5A, depending on the input-output voltage difference and ambient temperature.
3. Thermal Regulation: It includes thermal overload protection to prevent damage from excessive heat, ensuring reliable operation.
4. Short-Circuit Protection: Built-in current limiting ensures protection against short circuits.
5. Line and Load Regulation: Offers excellent line and load regulation, contributing to stable performance across different operating conditions.
6. Low Dropout Voltage: The regulator requires a small voltage difference between input and output for proper operation.
These features make the LM337IMPX suitable for use in a wide range of applications, including power supplies and battery-operated devices, where stable and adjustable negative voltage is required.

Package

The LM337IMPX is a voltage regulator typically packaged in a SOT-223 (Surface-Mounted) package. This package type is used for efficient heat dissipation and compact design, making it suitable for applications with space constraints.

Pinout

The LM337IMPX is a negative voltage regulator, specifically designed to provide a stable output voltage that can be adjusted from -1.2V to -37V. It is commonly used in applications requiring a regulated negative voltage supply. The LM337IMPX is typically available in a SOT-223 package, which has three pins. Here is a concise description of the pin configuration:
1. Pin 1 (Adjust): This pin allows for the adjustment of the output voltage. By connecting a resistor divider network between the output and the adjust pin, you can set the desired output voltage level.
2. Pin 2 (Output): The regulated negative output voltage is provided at this pin. It is the terminal where the load is connected to receive the stabilized voltage.
3. Pin 3 (Input): This pin receives the unregulated input voltage. The input voltage must be more negative than the desired output voltage by at least the dropout voltage to ensure proper regulation.
The LM337IMPX helps in providing a reliable and adjustable negative voltage supply for various electronic circuits and applications.
