Low Noise Power Supplies Come in Many Flavors: Part 1 - Linear Regulators

Kevin B. Scott - Senior Strategic Marketing Engineer Mar 23rd 2017
(In this three part series, we look at low noise portable power supplies using different topologies. Using a low noise linear regulator is a no-brainer for many of these applications, but in applications where a linear regulator may not be desired (due to efficiency, power dissipation or other constraints), low noise solutions ...

AN159: Measuring 2nV/√Hz Noise and 120dB Supply Rejection on Linear Regulators - The Quest for Quiet

Apr 4th 2016
AN159: Introduction A quiet, well regulated supply is important for optimum performance with a number of circuit applications. Voltage controlled oscillators (VCOs) and precision voltage controlled crystal oscillators (VCXOs) respond to small changes in their supply very quickly. Phase-locked loops (PLLs) require a stable supply ...

The LT0342 is a 200mA, 1.8V to 20V input, linear regulator that targets low noise RF and wireless circuits. It features an industry-leading 0.8µVRMS output noise (10Hz to 100kHz) and an impressive 79dB PSRR at 1MHz. Several customers have asked for ways to increase the current above 200mA while still maintaining low noise ...
