“Quiet” LDO Employs Unique Architecture to Cut Noise and Boost PSRR (.pdf download)

Intended for powering noise sensitive applications, Linear Technology has introduced the LT3042, a low dropout (LDO) linear regulator. This LDO uses a unique architecture that minimizes noise effects and optimizes PSRR. To understand the noise performance of this IC, we should first review power source noise characteristics..............
