That second regulated rail saves you an external LDO and its associated passives when you need a clean 2.2 V supply for an analog front-end or a low-voltage logic rail. ## Input range that squeezes the last drop out of a battery The 0.7 V minimum supply voltage means this part can start up and regulate from a single alkaline cell that has dropped below 1 V – the boost stage keeps the 4.3 V rail alive while the cell discharges down to 0.7 V. The 4.5 V maximum input covers two-series alkaline or a single Li-ion with headroom.","metaTitle":"TI TPS61098DSER Boost Converter + LDO, 0.7V–4.5V Input","metaDescription":"Texas Instruments TPS61098DSER dual-output PMIC: synchronous boost (4.3V/350mA) plus LDO (2.2V/200mA) in 6-WSON. 0.7V min input.
