LM2596R-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The TAEJIN LM2596R-ADJ is a monolithic integrated circuit designed for step-down switching regulator applications. It operates with a fixed internal oscillator frequency of 150kHz and supports an input voltage range up to 40V. The device provides an adjustable output voltage ranging from 1.2V to 37V, maintaining a maximum error of +/- 4% under line and load conditions. It delivers a continuous output current of 3.0A and incorporates thermal shutdown and current limit protection. The component is housed in a TO-263-5 surface-mount package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated 150kHz fixed-frequency oscillator eliminates the need for external timing components
• Includes TTL shutdown capability for low power standby mode control
• Built-in thermal shutdown and current limit protection circuits ensure operational safety

Voltage Regulators - DC DC Switching Regulators Applications

• Simple high-efficiency step-down (buck) regulators
• Efficient pre-regulators for linear regulators
• On-card switching regulators
• Positive to negative converter (buck-boost) configurations

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific part number corresponds to the adjustable output variant rather than fixed voltage versions. Confirm the package type matches the required PCB footprint, as variations exist between through-hole and surface-mount formats. Ensure the supplier source aligns with the manufacturer's authorized distribution channels to guarantee component authenticity and quality standards.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing buck converters requiring up to 3A load capacity with minimal external parts. The adjustable output version offers flexibility for custom voltage requirements within the specified range. Consider the thermal performance of the TO-263-5 package for heat dissipation needs in compact designs. Verify input voltage stability does not exceed the 40V absolute maximum rating.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2596 series of switching regulators, which are widely recognized for their ease of design and reliability in power management applications. The series includes both fixed and adjustable output variants, catering to diverse voltage conversion needs. The R suffix typically denotes the surface-mount package configuration, distinguishing it from through-hole alternatives.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Compatible substitutes include the Texas Instruments LM2596S-ADJ/NOPB and other LM2596 series devices from different manufacturers. Ensure pinout compatibility and electrical specifications match before substitution. Verify that alternative sources meet the same thermal and current handling requirements.
