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.
Optimize signal integrity with our ultra-low-noise LDOs.
Save power across a wide variety of applications with our low quiescent current LDOs.
Enhance system reliability with our robust LDOs featuring a wide input voltage range.
Reduce solution size with our small-size, high-performance LDOs.
The industry's most integrated smart AC/DC linear regulator
This nonmagnetic architecture helps achieve 75% efficiency and 2x the power density in AC/DC power compared to capacitor-drop designs. The TPS7A78 device removes EMI emissions from your AC/DC power supply and enables a tamper-proof power supply.
