LM2853MH-1.8

Voltage Regulators - DC DC Switching Regulators Overview

The LM2853MH-1.8 is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by National Semiconductor, now part of Texas Instruments. It provides a stable 1.8 V output voltage with a maximum load current capability of 150 mA. The device is housed in a compact MSOP-8 package, designed for space-constrained applications. It features internal protection mechanisms including thermal shutdown and current limiting to ensure reliable operation under fault conditions. The regulator operates with an input voltage range that supports efficient regulation while maintaining low quiescent current consumption, making it suitable for battery-powered portable electronics.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer marking as Texas Instruments due to the acquisition of National Semiconductor. Confirm the suffix MH indicates the MSOP-8 package variant. Ensure the -1.8 designation matches the required 1.8 V output specification. Check for RoHS compliance status if environmental regulations apply to your deployment. Validate authenticity through authorized distributors to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8 V output is required with moderate current demands up to 150 mA. Consider the MSOP-8 package size against available PCB real estate. Evaluate input voltage headroom to ensure proper dropout performance. Compare quiescent current specifications against other LDOs if battery life is critical. Verify thermal dissipation capabilities based on expected ambient temperatures and load currents.

Voltage Regulators - DC DC Switching Regulators Part Context

The LM2853 series belongs to National Semiconductor's family of low-dropout regulators designed for portable applications. The LM2853MH-1.8 specifically targets markets requiring small footprints and stable voltage regulation. As part of the broader LM285x lineup, it shares common architectural features like thermal protection but differs in output voltage and package options.
