LM2595T-ADJ/LF02

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595T-ADJ/LF02 is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a 150 kHz step-down voltage regulator. It accepts an input voltage range of 4.5 V to 40 V and provides a positive adjustable output voltage between 1.2 V and 37 V. The device delivers a maximum output current of 1 A through a single output channel. It is housed in a TO-220-5 package with formed leads for through-hole mounting. The operational junction temperature range spans from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply systems requiring buck conversion
• Pre-regulator circuits for linear regulators
• Efficient on-card regulation modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix LF02 corresponds to the TO-220-5 through-hole package configuration. Confirm RoHS compliance status matches current manufacturing standards. Ensure the adjustable output variant aligns with circuit design requirements rather than fixed voltage options. Cross-reference the manufacturer part number against official TI documentation to avoid obsolete or discontinued stock variations.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 1 A buck converter is required with an input voltage up to 40 V. The adjustable output allows flexibility for various load voltages between 1.2 V and 37 V. Choose the through-hole TO-220-5 package if board space permits and mechanical stability is preferred over surface-mount alternatives. Consider the 150 kHz switching frequency for balancing component size and efficiency.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2595 series of SIMPLE SWITCHER converters. It shares architectural similarities with the LM2596 but offers lower current capability at 1 A compared to the 3 A variants. The series is known for reducing design complexity by minimizing external passive components while maintaining robust performance in standard DC-DC applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-compatible replacements within the same family include other LM2595 variants with different packages or output configurations. Verify electrical parameters such as output current and voltage ranges match before substitution. Consult the latest TI datasheet for updated availability and recommended alternative part numbers.
