Power trends
Power density
You can further improve your application’s performance when you consider thermals. An LDO’s nature is to regulate a voltage by turning excess power into heat, making this integrated circuit a good fit for low-power or small VIN-to-VOUT differential applications. Choosing the right LDO with the right package is crucial to maximizing an application’s performance.

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 runtimes 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.

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 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 ADCs or DACs, helping you generate clean power for precision applications.
