TPS73225-EP: change to IC part with +-2.5Volt

Part Number:TPS73225-EP

I design a board like the

EEG Front-End Performance Demonstration Kit

 (SLAU443B) with the ADS1299 from TI.

There is a +-2.5Volt Power supply with a TPS732225 , TPS723225 and TPS60403

Is there an another powersupply  IC what have all includet? The Input range need to be from 2Volt to 5Volt and on the output is just the ADS1299.
