DESCRIPTIOn 

The LTe3045 is a high performance low dropout linear regulator featuring LTC's ultralow noise and ultrahigh PSRR architecture for powering noise sensitive applica-tions. Designed as a precision current reference followed by a high performance voltage bufer, the LT3045EDD#PBF 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 <<1uA in shutdown. The LT3045's wide output voltage range(OV 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 capa-bility and programmable power good to indicate output voltage regulation.
The LT3045EDD#PBF is stable withaminimum 10uF ceramic output capacitor. Built-in protection includes reverse-batteryprotection, reverse-current protection, internal current limit with foldback and thermal limit with hysteresis. The LT3045EDD#PBF is available in thermally enhanced 12-Lead MSOP and 10-Lead 3mm ×3mm DFN packages.
