TXS0206-29YFPRB

Overview

The TXS0206-29YFPRB is a voltage-level translating transceiver and low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It integrates an LDO to provide a stable supply for external memory devices, facilitating communication between MMC, SD Card, and Memory Stick interfaces. The device supports bidirectional data translation with four channels, operating within a supply voltage range of 1.1 V to 3.6 V on both sides. It features ESD protection and EMI filtering capabilities, packaged in a 20-pin DSBGA format suitable for surface-mount applications.

Feature Summary

• Integrates an LDO voltage regulator to power external memory cards directly from the system bus
• Provides bidirectional voltage translation for mixed-voltage system compatibility
• Includes built-in ESD protection and EMI filtering to ensure signal integrity

Applications

• MMC card interface circuits
• SD Card slot designs
• MemoryStick interface implementations

Procurement Notes

Verify the specific suffix '29' against the manufacturer's current datasheet to confirm pinout and electrical characteristics, as this variant includes an integrated LDO distinct from standard translators. Ensure the 20-DSBGA package footprint matches the PCB layout requirements. Cross-reference RoHS compliance status with the latest environmental declaration documents provided by Texas Instruments prior to final procurement.

Selection Notes

Select this component when a single IC solution is required to handle both voltage level shifting and power regulation for memory interfaces. It is appropriate for designs where board space is limited and eliminating discrete LDO components is preferred. Confirm that the target memory card operates within the supported voltage ranges and that the thermal performance of the DSBGA package meets the application's heat dissipation needs.

Part Context

This part belongs to the TXS0206A family of voltage translators from Texas Instruments. While standard variants like the TXS0206AYFPR focus solely on translation, the -29 suffix indicates the inclusion of an LDO regulator. This integration simplifies the design of portable electronic devices requiring reliable communication with various types of removable storage media.
