LM3206TL/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3206TL/NOPB is a miniature step-down DC-DC converter optimized for portable applications. It operates from a single Lithium-Ion cell, stepping down input voltages ranging from 3.25V to 5.5V to a fixed output of 3.09V. The device features a typical switching frequency of 2MHz, enabling the use of tiny surface-mount components. It includes internal synchronous rectification for high efficiency and offers current overload protection, thermal overload protection, and a soft start function. The shutdown mode reduces battery consumption significantly.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'TL' corresponds to the tape and reel packaging variant rather than tube packaging when sourcing. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance status as per manufacturer specifications. Ensure compatibility with the required 8-pin micro SMD footprint during procurement planning.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a fixed 3.09V output from a single-cell lithium-ion source. The 2MHz switching frequency allows for minimal external passive component sizes. Consider the fixed output constraint; if adjustable voltage is needed, an alternative part within the family must be chosen. Verify thermal management requirements due to the compact package size.
