LM2595S-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The UMW LM2595S-5.0 is a 150 kHz, 1 A step-down voltage regulator belonging to the SIMPLE SWITCHER power converter series. It operates with an input voltage range of 4.5 V to 40 V and provides a fixed 5 V output. The device utilizes a TO-263-5 surface-mount package and integrates a 1.2 V reference with ±4% accuracy across line and load conditions. Designed for high efficiency, it requires only four external components for implementation.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Provides fixed 5 V output with tight regulation accuracy
• Features thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

• Efficient buck regulators for general-purpose power supplies
• Pre-regulators for linear voltage regulators
• On-card switching regulators in embedded systems
• Positive-to-negative converter topologies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer marking on the component body to confirm UMW origin, as Texas Instruments also produces this part number. Check for the presence of the 'NOPB' suffix or RoHS compliance markings if environmental standards are required. Ensure the TO-263-5 package matches your PCB footprint specifications before ordering.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output at up to 1 A is required from a wide input voltage range. It is suitable for designs prioritizing simplicity and low component count over maximum current capacity. Consider thermal management requirements for the TO-263-5 package under full load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This device is part of the SIMPLE SWITCHER family, which emphasizes ease of use and compact design. The LM2595 series offers lower current capability compared to the LM2596 series, making it ideal for applications where 1 A is sufficient. It serves as a cost-effective solution for DC-DC conversion in consumer and industrial electronics.
