FUNCTIONAL DIAGRAM

APPLICATIONS INFORMATION

The LT3077 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 85mV. A 4.7µF reference bypass capacitor decreases output voltage noise

to 1.2μVRMS. The LDO’s wide bandwidth and high PSRR permit the use of small ceramic capacitors, saving bulk

capacitance and cost. The LT3077 is ideal for high-performance FPGAs, microprocessors, RF communication, and

noise-sensitive supply applications.

Output Voltage

The LT3077’s unity-gain operation provides virtually constant output noise, PSRR, and bandwidth independent of

the programmed output voltage. Output voltages are digitally selectable in 50mV increments from 0.5V to 1.2V,

100mV increments from 1.2V to 1.8V, and discrete levels at 2V, 2.5V, 3V, 3.3V, and 4.2V.
