Overview
The LT3045EMSE#TRPBF is a high-performance low dropout linear regulator produced by Analog Devices Inc. This regulator is designed with LTC’s ultralow noise and ultrahigh PSRR (Power Supply Rejection Ratio) architecture, making it ideal for powering noise-sensitive applications. The device operates over a wide output voltage range of 0V to 15V and can supply up to 500mA of current with a typical dropout voltage of 260mV. It features a precision current reference followed by a high-performance voltage buffer, enabling it to be easily paralleled for further noise reduction and increased output current.
