New products: Step-up Voltage Regulators U1V11F3, U1V11F5, and U1V11A

We have released three new step-up regulators that can boost input voltages as low as 0.5 V and have typical efficiencies between 70 and 90%. Unlike most boost regulators, these offer a true shutdown option that turns off power to the load. They also automatically switch to a linear down-regulation mode when the input voltage exceeds the output, making them great for powering electronics projects from 1 – 3 NiMH, NiCd, or alkaline cells or from a single lithium-ion cell.

These regulators are available with a 3.3 V or 5 V fixed output voltage or an adjustable output voltage (2 V – 5.25 V).

what is the name of the IC on U1V11A. Can i get the datasheet?
We are not disclosing that part (yet). Are you looking for some specification on our assembled board, or are you interested because you want to use the chip in your own design?
