Low noise & precision

Enhance power and signal integrity to improve system-level protection and accuracy

How can power ICs reduce inherent and system noise?

The need for low-noise LDO regulators and switching converters, precision monitoring and reliable protection is fundamental to enabling precision signal chains. For applications such as battery monitoring of electric vehicles, test and measurement, medical and more, TI uses dedicated power process technologies and advanced circuit and test techniques that increase accuracy, minimize distortion and reduce noise across both linear and switching power converters.
