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. We also help you meet nearly any regulator design challenge, from powering sensitive analog systems to extending battery life.
Our high-performance linear power regulators and low-voltage regulators feature low noise, low IQ and wide VIN ranges. Our LDO regulators are available in small package sizes and for automotive applications.
The industry’s leading ultra-low noise, high-PSRR and low-IQ LDO regulator
This ultra-small LDO combines ultra-low noise of 7 µVRMS and high PSRR with low IQ and fast transient response. The TPS7A20 provides flexibility, low-power consumption and signal integrity to improve system lifetime and performance of your electronics.
Power management is at the center of enabling the continued integration of electronics in our lives. For decades, TI has been at the forefront of developing new process, packaging and circuit-design technologies to deliver the best power devices for your design. Check out our featured LDOs below, designed to help you address power density, low IQ and low noise and precision challenges.
LDOs for power density
Designing power supplies for space-constrained applications requires regulators that can operate efficiently in a small form-factor. Our LDOs help solve power density design challenges by offering low-dropout operation, improved thermal performance and small solution size. Low-dropout operation minimizes dissipation and improves thermal performance by facilitating heat transfer away from the package. Our LDOs are available in several small packages such as DSBGA (<1 mm2), X2SON (1 mm2) and SON (4 mm2), in addition to common leaded packages, helping you design for high power density.
LDOs for low quiescent current (IQ)
We understand that achieving ultra-low quiescent current (IQ) shouldn’t compromise your system performance. We offer regulators with low standby power combined with excellent load transient response so that you can achieve the longest battery run times while maintaining key performance. Our linear regulator portfolio includes low-IQ LDOs with input voltages as high as 100 V to help you with your low-standby power needs.
LDOs for low noise & precision
We can help solve your low-noise design challenges with a broad portfolio of low-noise and high power-supply rejection ratio (PSRR) regulators. High PSRR over a wide bandwidth (for example, 40 dB at 1 MHz) enables the LDO to filter switching noise emanating from upstream DC/DC converters. Low-noise (<5 µVRMS) outputs minimize low-frequency noise to maintain the signal integrity of sensitive analog circuitry such as analog-to-digital converters (ADCs) or digital-to-analog converters (DACs), helping you generate clean power for precision applications.
