Reduce solution size: Use small-size, high performance LDOs

The complexity and density of today's electronic designs equate to a limited amount of PCB space. To address the trend toward ever-smaller electronics, LDOs must deliver the same performance while consuming as little space as possible. TI offers many LDOs that address the high-performance requirements and tiny solution size.
