LM2595T-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595T-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER® step-down voltage regulator operating at a fixed 150 kHz switching frequency. It delivers a maximum output current of 1 A with a fixed 5 V output. The device accepts an input voltage range from 4.5 V to 40 V. It features internal frequency compensation and a fixed-frequency oscillator, reducing external component count. The unit operates within a temperature range of -40°C to +125°C and utilizes a TO-220-5 package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage power switch rated for up to 40 V input
• Fixed 150 kHz oscillation frequency simplifies design and minimizes size
• Internal frequency compensation reduces required external components
• Thermal shutdown and current limit protection ensure operational reliability

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply systems
• On-card regulation for boards powered by bus supplies
• Efficient pre-regulators for linear regulators

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' indicates lead-free status and RoHS compliance per manufacturer specifications. Confirm the 'T' designation corresponds to the TO-220-5 through-hole package variant rather than surface-mount options. Cross-reference the specific revision level against the official datasheet to ensure compatibility with existing thermal management designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from inputs up to 40 V. It is suitable for applications needing 1 A continuous current in a through-hole configuration. Consider alternatives if higher efficiency at light loads or adjustable output voltages are necessary. Ensure adequate heatsinking is planned due to the linear-like dissipation characteristics under high differential voltages.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2595 series of SIMPLE SWITCHER power converters. The series is designed for ease of use with minimal external components. The LM2595 specifically targets 1 A applications, distinguishing it from the 3 A LM2596 and 0.5 A LM2594 variants within the same family architecture.
