Dual-Output Boost Plus LDO in a 1.5x1.5 mm WSON
The TPS610981DSET integrates a synchronous step-up boost converter and a separate linear LDO regulator in a single 6-WSON (1.5x1.5 mm) package. The boost output delivers 3.3 V at 350 mA, while the LDO provides a second 3 V rail at 200 mA — enough to power a small sensor node's radio and MCU from a single battery that may sag to 0.7 V.
Input Range Down to 0.7 V — Battery-Friendly Operation
The supply range spans 0.7 V to 4.5 V, which lets the part extract energy from a single alkaline or Li-ion cell well into its discharge curve.
