Realize unmatched PSRR performance for noise-sensitive applications

Micrel's Ripple Blocker™ technology provides a simple, space saving and low cost solution for reducing power supply noise. The technology offers substantial noise reduction due to about a 60dB PSRR performance up to 10MHz. The Ripple Blocker™ family of devices is easy to use and improves the signal-to-noise ratio in a number of leading edge noise sensitive applications.

Ideal for use in:

Phones
Smart Phone Cameras, RF Power
Tablets
Tablet PC/Notebook Computers
Auto
Automotive and Industrial
