LM2595T-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595T-5.0 is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a 1A step-down voltage regulator with a fixed 5V output. It operates on a 40V maximum input voltage range, starting from a minimum of 4.5V. The device utilizes pulse width modulation control at a nominal switching frequency of 150kHz. Packaged in a TO-220 ZIP-5 surface-mount format, it supports an operating temperature range from -40°C to +125°C. Key electrical parameters include a maximum output current of 1A and a typical static current of 5mA.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates the TO-220 ZIP-5 package variant rather than standard DIP or other form factors. Confirm the '-5.0' designation ensures the fixed 5V output requirement is met. Check for 'NOPB' suffix if lead-free compliance is mandatory for the assembly process. Ensure the supplier provides original manufacturer documentation to validate authenticity against counterfeit risks common in legacy power management ICs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from higher voltage rails up to 40V. Choose the TO-220 ZIP-5 package for applications needing moderate thermal dissipation capabilities combined with surface-mount convenience. Consider the 150kHz switching frequency for balancing efficiency and passive component size. Evaluate the 1A current limit against peak load demands to ensure adequate headroom for transient conditions without exceeding thermal limits.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2595 series of SIMPLE SWITCHER regulators, designed for straightforward buck conversion applications. It shares architectural similarities with the LM2596 and LM2594 but offers distinct current ratings and package options. The series is characterized by its ease of use, requiring few external components to achieve stable regulation. It serves as a robust solution for industrial and commercial power distribution where space and cost efficiency are prioritized alongside performance stability.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2595S-5.0/NOPB: Offers identical electrical specifications but utilizes a TO-263 (D2PAK) surface-mount package instead of TO-220 ZIP-5. Verify footprint compatibility before substitution. LM2596T-5.0: Provides similar functionality but may differ in thermal characteristics or exact pinout details; consult datasheets for direct interchangeability confirmation.
