LM2595SX-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595SX-12/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments. It operates with an input voltage range of 4.5 V to 40 V and provides a fixed 12 V output at up to 1 A. The device integrates a 150 kHz switching frequency, 5 mA typical quiescent current, and a shutdown feature. Packaged in SOIC-8 (SOT-223), it supports operation from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a 150 kHz oscillator for efficient power conversion
• Includes internal error amplifier and current limit protection
• Supports low-power standby via external shutdown control

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Input voltage step-down for industrial equipment
• Power supply stages for communication modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'SX' indicates the SOT-223 package variant rather than standard SOIC. Confirm 'NOPB' denotes lead-free and RoHS compliance. Ensure the specific revision matches design requirements as TI may update documentation without changing part numbers.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V output is required from high-voltage inputs up to 40 V. It is suitable for designs needing moderate efficiency with minimal external components. Consider thermal management due to the small surface-mount package size under full load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LM2595 family of monolithic integrated circuits designed to simplify the design of step-down switching regulators. This series offers a cost-effective solution compared to discrete component implementations while maintaining reliable performance across wide input voltage ranges.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2595SX-12: Original non-RoHS version. LM2596SX-12: Higher current capability but different pinout. LM2594SX-12: Lower current rating. Verify pin compatibility and thermal characteristics before substitution.
