Overview for Linear Regulator (LDO)

TI has an LDO that fits your requirements, along with design resources and expertise

Low droput regulators (LDOs) are a simple, inexpensive way to regulate an output voltage that's powered from a higher voltage input. They range across many different features such as low noise, wide Vin, small size, low Iq, and processor attach. With over 500 devices reanging in many applications, robust quick selection capabilities, and best-in-class performance, TI has the most complete LDO portfolio in the industry.
