LM2852XMXA-2.5

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852XMXA-2.5 is a synchronous step-down switching regulator from the SIMPLE SWITCHER family, manufactured by Texas Instruments following its acquisition of National Semiconductor. It delivers a fixed 2.5 V output with a maximum current capability of 2 A. The device operates within an input voltage range of 2.85 V to 5.5 V and supports selectable switching frequencies of 500 kHz or 1500 kHz. It utilizes a 14-pin HTSSOP package and functions across an extended temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer origin carefully, as the component was originally designed by National Semiconductor but is now produced and distributed by Texas Instruments. Confirm that the specific suffix indicates the correct fixed output voltage variant. Ensure the package type matches the required PCB footprint and thermal management strategy for the target application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this regulator when a fixed low-voltage output is required without external resistor networks. Consider the 2 A current limit against peak load demands. Evaluate the trade-off between the 500 kHz and 1500 kHz frequency options based on available inductor size constraints and electromagnetic interference requirements. Verify compatibility with the system's input voltage supply rails.
