LM2825N-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2825N-5.0 is a fixed-output step-down switching regulator manufactured by Texas Instruments, designed for efficient voltage conversion in power supply applications. It integrates a 1.5 A current-limiting switch and operates with an input voltage range of 4 V to 40 V. The device provides a stable 5.0 V output at up to 500 mA, featuring thermal shutdown and current limiting for robust protection. Operating at a typical frequency of 150 kHz, it utilizes pulse-width modulation to regulate the output. The component is housed in an 8-pin MDIP package, suitable for through-hole mounting, and supports a wide operating temperature range from -40 °C to 125 °C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' or equivalent to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm that the procurement channel provides original manufacturer documentation to validate the part authenticity and traceability. Ensure the ordering quantity aligns with standard tube packaging requirements rather than bulk or tape-and-reel formats, as this model typically ships in multi-dip tubes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5.0 V output is required from a variable or higher input voltage source within the 4 V to 40 V range. It is appropriate for designs prioritizing simplicity and cost-effectiveness over adjustable output flexibility. Consider the 150 kHz switching frequency regarding EMI constraints and external component sizing. Ensure the load current does not exceed 500 mA to maintain optimal efficiency and thermal performance.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2574xx series of switching regulators, which are known for their simplicity and reliability in step-down configurations. Unlike adjustable variants, the fixed-output version eliminates the need for external feedback resistors, simplifying the design process. It serves as a direct replacement for older linear regulators in applications where efficiency and heat dissipation are critical concerns.
