LM2594M-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594M-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator operating at a fixed 150 kHz switching frequency. It provides a fixed 5 V output with a maximum load current of 500 mA. The device accepts an input voltage range from 4.5 V to 40 V and utilizes an SOIC-8 surface-mount package. It features a typical quiescent current of 5 mA and supports an operating temperature range from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic buck converter topology for efficient step-down regulation
• Fixed internal feedback network providing precise 5 V output voltage
• Built-in thermal shutdown and current limit protection mechanisms

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation in distributed power architectures
• Pre-regulation stages for linear post-regulators
• Efficient battery-powered systems requiring step-down conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per the manufacturer's latest documentation. Confirm the 'M' suffix corresponds to the SOIC-8 package variant rather than other package options within the LM2594 family. Ensure the fixed 5.0 V output version matches the design requirement, distinct from adjustable or other fixed voltage variants.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from an input voltage up to 40 V. The 500 mA current rating suits low-to-medium power applications. Consider the 150 kHz frequency for balancing component size and efficiency. Verify that the SOIC-8 thermal performance meets the application's heat dissipation needs without additional heatsinking.
