The LT3045EMSE#PBF is a low dropout (LDO) voltage regulator manufactured by Analog Devices. It is a linear regulator that has a wide input voltage range of 2.5V to 20V and a maximum output current of 500mA, providing excellent performance with an ultra-low noise output and an ultrahigh power supply rejection ratio (PSRR). This ultralow noise and high PSRR ensures only the desired current is supplied, providing clean power for a variety of applications. The LT3045EMSE#PBF also features an adjustable fast-startup current limit that enables the load to be limited to a safe level during system startup. The package for this part is MSOP-8, and it is fully qualified for automotive applications.
