The LT3072 is a low voltage, UltraFast™ transient response, dual channel linear regulator. The device supplies up to 2.5A per channel with a typical dropout voltage of 80mV. A 0.1µF reference bypass capacitor decreases output voltage noise to 12µVRMS. The wide bandwidth and high PSRR permit the use of small ceramic capacitors, saving bulk capacitance and cost. The LT3072 is ideal for high performance FPGAs, microprocessors and sensitive RF communication supply applications.
Independent output voltages are digitally selectable in 50mV increments from 0.6V to 1.2V and in 100mV increments from 1.2V to 2.5V. Output current monitors provide diagnostics and program the precision current limit. The LT3072 incorporates a unique tracking feature (VIOC) to control the upstream buck regulator(s) powering the inputs. VIOC adaptively servos the buck regulator to maintain the LT3072 input-to-output voltage differential to 300mV at maximum load and 450mV at light load, minimizing power dissipation with less input capacitance. Internal protection circuitry includes UVLO, OVLO, reverse-current protection, current limiting and thermal shutdown. The LT3072 is available in a low profile (0.75mm) 36-lead 4mm × 7mm QFN package.
