LM2852YMXAX-2.5

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852YMXAX-2.5 is a synchronous step-down switching voltage regulator from Texas Instruments, designed for high-efficiency power conversion in compact applications. It integrates a 2A output current capability with an adjustable or fixed 2.5V output option within the SIMPLE SWITCHER family. The device operates over an input voltage range of 2.85V to 5.5V and supports switching frequencies of 500kHz or 1.5MHz to optimize external component size. Packaged in a 14-pin HTSSOP with exposed pad for thermal management, it features comprehensive protection mechanisms including overcurrent, thermal shutdown, and soft-start functionality.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix configuration against the manufacturer datasheet to ensure correct output voltage and package variant. Confirm RoHS compliance status and lead times through authorized distributors as availability may vary. Check for pin compatibility if replacing existing designs, noting that the exposed pad requires proper thermal grounding on the PCB layout.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this regulator when a fixed 2.5V output is required alongside high efficiency and small footprint. Consider the 14-pin HTSSOP package for thermal performance and board space optimization. Evaluate the need for 500kHz versus 1.5MHz operation based on inductor size constraints and electromagnetic interference requirements in the target application environment.
