LM2825N-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2825N-ADJ/NOPB is a synchronous step-down switching voltage regulator manufactured by Texas Instruments. It integrates a high-side N-channel MOSFET and a low-side synchronous rectifier to deliver up to 1A of output current. The device operates with an input voltage range of 4.5V to 40V and supports adjustable output voltages from 1.23V to 15V. It features a fixed switching frequency of 150kHz and includes internal compensation for stable operation. The component is housed in an 8-pin PDIP package and functions within a temperature range of -40°C to 85°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact package type, as DIP variants may differ from surface-mount equivalents. Confirm that the NOPB suffix indicates lead-free and RoHS compliance. Ensure the supplier provides official datasheets matching the Texas Instruments part number to avoid counterfeit components. Check for specific handling requirements during storage and assembly.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust, adjustable DC-DC converter is needed for moderate current applications. It is suitable for designs requiring wide input voltage ranges and high efficiency without external compensation components. Consider the PDIP package if through-hole mounting is required for prototyping or specific mechanical constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2825 family of integrated power switches. It is designed as a drop-in replacement for older discrete solutions, offering higher integration and better performance. The LM2825 series is commonly used in applications where space and efficiency are critical but extreme miniaturization is not the primary constraint.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct substitutes like the LM2825HN-ADJ/NOPB for pin-compatible alternatives. Verify electrical specifications match before substitution.
