Bluetooth converter regulator with fixed 1.9V rail
The TPS62732DRYT is a single-output regulator from Texas Instruments, designed specifically for Bluetooth converter applications. It delivers a fixed 1.9V output from an input range of 1.9V to 3.9V — a tight window that matches single-cell Li-ion or two-cell alkaline battery profiles common in wireless modules. That simplifies the external component count but locks the design to that one rail.
Package and thermal layout for 6-UFDFN
Housed in a 6-UFDFN package with supplier device package 6-SON (1.45x1), the footprint is tiny — roughly 1.45 mm × 1 mm. The 6-UFDFN is a leadless package — rework requires a hot-air station with a fine nozzle; the small pad pitch makes hand-soldering unreliable.
The lower end suits cold-chain or outdoor deployments; the upper end keeps the regulator within spec in a sealed enclosure with moderate self-heating.
Production orders are standard — no LTB risk, no last-time-buy math needed.
