LM2841XMKX-ADJL/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2841XMKX-ADJL/NOPB is a step-down DC/DC regulator from the LM284x series, manufactured by Texas Instruments. It features an input voltage range of 4.5 V to 42 V and provides an adjustable output voltage between 0.765 V and 34 V. The device supports a maximum output current of 300 mA with a single output channel. Operating at a switching frequency of 1.25 MHz, it utilizes a buck topology for efficient power conversion. The component is housed in a TSOT-23-6 surface-mount package, measuring 2.97 mm in length, 1.65 mm in width, and 0.87 mm in height. It operates within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a high-frequency buck converter capable of handling up to 42 V input voltages
• Provides adjustable output regulation within a wide voltage window
• Utilizes a compact thin SOT-23 package for space-constrained designs
• Supports operation across extended industrial temperature ranges

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial control systems requiring isolated or non-isolated power stages
• Automotive electronics operating on 12 V or 24 V nominal bus lines
• Distributed power architectures in embedded computing platforms
• Battery-powered devices needing efficient step-down regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix 'ADJL' corresponds to the adjustable output variant as documented in the official Texas Instruments datasheet. Confirm the package type matches the required TSOT-23-6 footprint for PCB layout compatibility. Ensure the supplier source provides genuine components with traceable manufacturing lot codes to guarantee reliability in critical applications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 300 mA output current is sufficient for the load requirements. Consider the 1.25 MHz switching frequency for balancing efficiency and external component size. Evaluate the thermal performance within the -40°C to +125°C range against the expected ambient conditions. Compare against the LM2840 (100 mA) and LM2842 (600 mA) if current needs differ.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM284x family of SIMPLE SWITCHER regulators, which includes the LM2840, LM2841, and LM2842 variants. These devices share similar architectural features but differ primarily in their maximum output current capabilities. The LM2841 specifically targets the 300 mA segment, bridging the gap between lower-current and higher-current solutions within the same pin-compatible package family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2840XMKX-ADJL/NOPB offers identical functionality with reduced 100 mA output current. LM2842XMKX-ADJL/NOPB provides increased 600 mA capacity while maintaining the same package and electrical characteristics.
