LM2825N-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2825N-ADJ is a step-down switching voltage regulator manufactured by Texas Instruments. It operates with an input voltage range up to 40 V and provides a single adjustable output voltage from 1.23 V to 15 V. The device supports a maximum output current of 1 A and features a switching frequency of 150 kHz. It is housed in a 24-pin PDIP package and functions within a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Adjustable output voltage capability via external resistor network
• Integrated current limiting for protection
• Supports standard buck converter topologies

Voltage Regulators - DC DC Switching Regulators Applications

• General-purpose DC-DC conversion
• Battery-powered systems requiring regulated lower voltages

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) against the manufacturer's current product status, as this component may be obsolete or superseded. Confirm pinout compatibility if replacing existing designs. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed-output buck regulator is insufficient and an adjustable voltage range between 1.23 V and 15 V is required. Consider the 150 kHz switching frequency for trade-offs between component size and efficiency. Verify that the 1 A output current meets the load requirements before finalizing the design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2825 family of switching regulators. It is distinct from the UC2825 PWM controller series, which serves different control functions. The LM2825 integrates the power switch and control logic into a single monolithic IC, simplifying the design of step-down converters compared to discrete solutions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Public sources indicate this part number is obsolete. Check for direct replacements such as the LM2575 series or newer TI buck regulators. Verify electrical compatibility including input voltage, current capacity, and pin configuration before substitution.
