LT3073AV#TRPBF

LT®3073 is a low voltage, ultra-low-noise and ultra-fast transient response linear regulator. The device supplies up to 3A with a typical dropout voltage of 45mV. A 4.7µF reference bypass capacitor decreases output voltage noise to 1.2µVRMS. The wide bandwidth and high PSRR permit the use of small ceramic capacitors, saving bulk capacitance and cost. The LT3073 is ideal for powering high-performance FPGAs, data converters, RF, and noise-sensitive signal chain applications. A precision current monitor provides power monitoring for system energy management, while precision current limiting allows users to minimize input power supply size and cost. Built-in protection includes UVLO, internal current limit, and thermal shutdown with hysteresis. Typical applications are RF power supplies: PLLs, VCOs, mixers, LNAs, PAs, high speed/high precision data converters, low-noise instrumentation, post-regulator for switching supplies, FPGA and DSP power supplies, medical applications.
