Improve your system performance with our  LDO linear regulators

With the largest portfolio of LDOs, we have the right one for you

Low-dropout (LDO) linear regulators are a simple, inexpensive way to regulate an output voltage that is powered from a higher voltage input in a variety of applications. Browse our portfolio of over 500 devices with features such as low noise, wide input voltage (VIN), small package size, low quiescent current (IQ), processor attach and the industry's first smart AC/DC linear regulator.

Low noise

Optimize signal integrity with our ultra-low-noise LDOs.

Low IQ

Save power across a wide variety of applications with our low quiescent current LDOs.

Wide VIN

Enhance system reliability with our robust LDOs featuring a wide input voltage range.

Small size

Reduce solution size with our small-size, high-performance LDOs.

The industry's lowest quiescent current (25-nA), ultra-small LDO regulator

This ultra-small LDO combines low IQ with fast transient response to improve system lifetime and performance. The TPS7A02 helps reduce solution size by 70%, increase application run times and extend the battery life of your electronics.
