About this document
Maxim AN 3656 by Rolf Dieter Kaschke is a document available to read on EtoBox.
Application Note 3656 discusses a simple RC filter with an external transistor that reduces low-dropout regulator (LDO) noise by over 46dB, achieving a noise floor of 7nV/√Hz. The design is particularly suited for low-noise applications like instrumentation and high-quality audio, utilizing a feedback loop to maintain voltage regulation. The note includes details on component selection and circuit configuration for optimal performance.
