LM2594N-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594N-5.0/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, housed in an 8-pin MDIP package. It operates with a minimum input voltage of 4V and a maximum of 40V, delivering a fixed 5V output at up to 500mA. The device features a switching frequency of approximately 150kHz and includes internal compensation for minimal external component requirements. It supports a wide operating temperature range from -40°C to +125°C and incorporates thermal shutdown protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated thermal shutdown protection safeguards against overheating during fault conditions.
• Internal frequency compensation reduces the need for external components, simplifying design.
• Fixed 5.0V output option eliminates the requirement for external feedback resistors.

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for distributed power architectures
• Standard 5V line regulation prior to further filtering
• Efficient buck conversion from higher bus voltages

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific part number corresponds to the through-hole MDIP package variant rather than surface-mount options. Confirm that the fixed 5.0V output specification aligns with the target circuit requirements, as adjustable versions exist within the same series. Ensure compliance with RoHS standards if required by the final assembly specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required with moderate current capacity up to 500mA. The through-hole MDIP package is suitable for prototyping or applications where manual soldering is preferred over SMT processes. Consider the 40V maximum input limit to ensure compatibility with the source voltage rails.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2594 family of SIMPLE SWITCHER regulators, designed for high-efficiency DC-DC conversion. It serves as a through-hole alternative to surface-mount variants like the LM2594M series. The family is characterized by low external component count and robust protection features for general-purpose power management.
