LM2595T-12

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595T-12 is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a 150 kHz step-down voltage regulator. It provides a fixed 12 V output with a maximum current of 1 A. The device accepts an input voltage range of 4.5 V to 40 V and operates within a temperature range of -40 °C to +125 °C. It utilizes a TO-220-7 through-hole package and features a shutdown pin for low standby current consumption.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic switching regulator designed for high-efficiency DC/DC conversion
• Fixed internal feedback network ensures stable 12 V output without external adjustment components
• Includes thermal shutdown and current limit protection for robust operation under fault conditions

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation in distributed power systems
• Pre-regulation for linear post-regulators
• Efficient buck converters for battery-powered equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix against the manufacturer datasheet, as variations such as NOPB indicate lead-free compliance. Confirm the package type matches the required PCB footprint, typically TO-220-7 for this variant. Ensure the fixed 12 V output aligns with system requirements, as adjustable versions exist within the same family. Cross-reference the revision level to guarantee compatibility with existing design files.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V output is required at up to 1 A with minimal external parts. It is suitable for designs prioritizing efficiency over ultra-low quiescent current. Consider the TO-220-7 package for through-hole assembly needs. Compare against the LM2596 series if higher current capacity is necessary, or the LM2594 if lower current suffices.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the SIMPLE SWITCHER family, known for integrating the controller, switch, and diode into a single IC. It simplifies power supply design by reducing component count compared to discrete solutions. The LM2595 series specifically targets 1 A applications, bridging the gap between lower-current regulators and higher-power counterparts like the LM2596.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2595T-12/NOPB is the direct lead-free equivalent. LM2596T-12 offers similar functionality but with increased current capability. LM2594T-12 provides comparable performance at reduced current levels.
