LM2852YMXAX-0.8/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852YMXAX-0.8/NOPB is a synchronous buck regulator from the National Semiconductor LM2852 family, now under Texas Instruments. It features a fixed 0.8V output voltage and supports up to 2A continuous load current. The device operates with an input voltage range of 2.85V to 5.5V and offers selectable switching frequencies of 500kHz or 1500kHz. It utilizes a 14-pin HTSSOP package and functions within a junction temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer origin as National Semiconductor was acquired by Texas Instruments; ensure the NOPB suffix confirms lead-free/RoHS compliance. Confirm the specific output voltage variant matches the design requirement, as the LM2852 series includes multiple fixed voltage options. Check the package marking for authenticity against official TI datasheets.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed low-voltage output is required without external feedback resistors. The choice between 500kHz and 1500kHz switching frequencies depends on inductor size constraints versus EMI requirements. Ensure the input voltage stays within the 2.85V to 5.5V range for proper regulation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2852 Simple Switcher family of synchronous buck regulators. The 'Y' indicates a specific thermal/package code, 'M' denotes the HTSSOP package, 'A' refers to the tape and reel packaging, and 'X' often signifies a specific revision or testing level. The '-0.8' specifies the fixed 0.8V output version.
