The Texas Instruments TPS61100RGER is a dual-output power-management IC that integrates a synchronous step-up (boost) converter and a linear LDO regulator in a single 24-VQFN package measuring 4 mm by 4 mm.
Supply input spans 0.8 V to 3.3 V, so the part can start up from a single alkaline cell that has dropped below 1 V and continue operating as the battery drains.
Yes, the TPS61100RGER is listed as RoHS compliant.
Like any switching regulator, the TPS61100RGER needs an external inductor, input and output capacitors, and feedback resistors to set the output voltages. The LDO output also requires a bypass capacitor. TI provides a reference design and typical application circuit in the datasheet.
