Mounting type Surface Mount compatible with standard reflow profiles

Supplier device package 6-WSON 2 x 2 mm

Moisture handling Follow TI WSON handling guidelines for storage and reflow

Lifecycle

Status Active and suitable for ongoing designs

Not nearing discontinuation based on current industry status for the TPS745 family

Equivalent or alternative models

- TPS745xxPQWDRVRQ1 family variants with different fixed output voltages for the same current rating and package footprint

- TLV755P-Q1 500 mA LDO, automotive-grade, similar current rating with different PSRR and noise profile

- TPS7A21-Q1 300 mA LDO, automotive-grade, for lower current but higher PSRR needs

- TLV767-Q1 1 A LDO, automotive-grade, for designs needing more current

- TPS7A20-Q1 300 mA high-PSRR LDO, automotive-grade, for sensitive analog and RF rails

- Always verify pinout, package, dropout, PSRR, and enable or power-good functions for compatibility
