The 1N5619US is an Ultra low noise, high PSRR, 200 mA Power by Microchip. It is an integrated circuit which provides ultra low noise, typically 300uVrms, and is suitable for powering Analog-to-Digital Converters (ADCs), amplifiers, data converters, amplifiers and similar low power analog circuits. It features low quiescent current draw, excellent PSRR and ripple rejection and good transient response. It is housed in a thermally enhanced, SOIC-8 package.
