LM2595T-5.0/LF02

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595T-5.0/LF02 is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a 150 kHz step-down voltage regulator. It provides a fixed 5V output with a maximum current of 1A. The device accepts an input voltage range from 4.5V to 40V. It utilizes pulse-width modulation control and operates within a temperature range of -40°C to 125°C. The component is housed in a TO-220 package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic switching regulator designed for high-efficiency step-down conversion
• Fixed internal feedback network ensures stable output without external adjustment components
• Built-in thermal shutdown and current limiting protect against overload conditions

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply systems requiring buck conversion
• Pre-regulator circuits for linear regulators
• Battery-powered applications needing efficient voltage stepping

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix LF02 against official Texas Instruments documentation to confirm lead-free status and tape-and-reel packaging specifications. Ensure compatibility with standard TO-220 mounting hardware. Cross-reference the part number with the latest datasheet revision to confirm availability and manufacturing status.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output at 1A is required from a higher input voltage rail up to 40V. The TO-220 package facilitates heat dissipation for moderate power levels. Consider the 150kHz switching frequency for balancing component size and efficiency requirements in space-constrained designs.

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 (3A) and LM2594 (0.5A) but is specifically rated for 1A output. The series is known for minimizing external component count while maintaining robust performance in DC-DC conversion tasks.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2595S-5.0/NOPB offers identical electrical characteristics in a surface-mount TO-263 package. LM2596T-5.0 provides higher current capacity (3A) in the same through-hole form factor. Verify pinout compatibility before substituting.
