Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2840XMK-ADJL/NOPB

LM2840XMK-ADJL/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2840XMK-ADJL/NOPB is a step-down DC/DC regulator from the LM284x family, manufactured by Texas Instruments. It operates with an input voltage range of 4.5 V to 42 V and provides an adjustable output voltage between 765 mV and 34 V. The device supports a maximum output current of 100 mA and utilizes a fixed switching frequency of 550 kHz. It is housed in a thin SOT-23-6 package (SOT-23-THIN-6) suitable for surface-mount installation. The component functions within a temperature range of -40°C to +125°C and includes shutdown functionality.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated buck topology for efficient step-down voltage conversion
Adjustable output voltage capability via external resistor network
Compact thin SOT-23-6 package design for space-constrained applications

Voltage Regulators - DC DC Switching Regulators Applications

Battery-powered portable electronics requiring regulated power supply
Industrial control systems utilizing wide input voltage ranges

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix ADJL indicates the adjustable version when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the thin SOT-23-6 footprint matches the PCB layout requirements. Cross-reference the datasheet revision date to confirm technical specifications align with current production standards.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a 100 mA output current from high input voltages up to 42 V. The adjustable output feature allows flexibility in setting precise voltage levels. Consider the thermal performance in the thin SOT-23 package under load. Compare against the LM2841 and LM2842 variants if higher current capabilities such as 300 mA or 600 mA are required for the application.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM284x SIMPLE SWITCHER family of regulators. These devices are designed to offer high efficiency in a small form factor. The family includes variants with different current ratings, sharing similar input voltage ranges and switching frequencies. The LM2840 specifically targets lower current applications compared to its 300 mA and 600 mA counterparts.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2840XMK-ADJL/NOPB serves as the base part number. LM2840XQMK/NOPB is available for automotive-grade requirements. LM2841XMK-ADJL/NOPB offers 300 mA output. LM2842XMK-ADJL/NOPB provides 600 mA output. Verify pin compatibility and thermal characteristics when substituting.
