LT304x PSRR Linear Regulators

Analog Devices Inc. LT304x PSRR Linear Regulators are high-performance low dropout regulators with ultralow noise and ultrahigh PSRR architecture for powering noise-sensitive applications. The regulator is designed as a precision current reference followed by a high-performance voltage buffer. The LT304x can be paralleled to further reduce noise, increase output current, and spread heat on the PCB.
