LT3072IUFF#PBF

LT3072 is a low voltage, UltraFast™ transient response, dual channel linear regulator. The wide bandwidth and high PSRR permit the use of small ceramic capacitors, saving bulk capacitance and cost. It is ideal for high performance FPGAs, microprocessors and sensitive RF communication supply applications. It 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 device 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. It is used in application such as FPGA, DSP and microprocessor power supplies, low noise RF power supplies, high-speed servers and storage devices, post buck regulation and supply isolation etc.
