Introduction
The LT3045 is a high performance low dropout linear regulator featuring LTC’s ultralow noise and ultrahigh PSRR architecture for powering noise sensitive applications. Designed as a precision current reference followed by a high performance voltage buffer, the LT3045 can be easily paralleled to further reduce noise, increase output current and spread heat on the PCB. The device supplies 500mA at a typical 260mV dropout voltage. Operating quiescent current is nominally 2.2mA and drops to <1µA in shutdown. The LT3045’s wide output voltage range (0V to 15V) while maintaining unity - gain operation provides virtually constant output noise, PSRR, bandwidth and load regulation, independent of the programmed output voltage. Additionally, the regulator features programmable current limit, fast start - up capability and programmable power good to indicate output voltage regulation. The LT3045 is stable with a minimum 10µF ceramic output capacitor. Built - in protection includes reverse - battery protection, reverse - current protection, internal current limit with foldback and thermal limit with hysteresis. The LT3045 is available in thermally enhanced 12 - Lead MSOP and 10 - Lead 3mm × 3mm DFN packages.
