New Products: Low input voltage step-up regulators



We are excited to announce some new boost regulators that operate from input voltages as low as 0.5 V:

[li]U1V11A (2 V to 5.25 V adjustable output)[/li]
[li]U1V11F3 (3.3 V fixed output)[/li]
[li]U1V11F5 (5 V fixed output)[/li][/ul]

These switching voltage regulators feature a true shutdown option that disconnects power to the load (typical boost regulators pass the input voltage directly through to the output when they are disabled). In addition, they automatically switch to a linear down-regulation mode when the input voltage exceeds the set output voltage. The input current on these regulators can be as high as 1.2 A, and they have typical efficiencies of 70% to 90% when boosting.
