LT3070EUFD#PBF

LT3070 is a low voltage, UltraFast™ transient response linear regulator. This device's high bandwidth permits the use of low ESR ceramic capacitors, saving bulk capacitance and cost. This devices ’s features make it ideal for high performance FPGAs, microprocessors or sensitive communication supply applications. The IC incorporates a unique tracking function to control a buck regulator powering the device’s input. This tracking function drives the buck regulator to maintain the device’s input voltage to VOUT + 300mV, minimizing power dissipation. Internal protection includes UVLO, reverse-current protection, precision current limiting with power foldback and thermal shutdown. It is widely used in application such as FPGA and DSP supplies, ASIC and microprocessor supplies, servers and storage devices, post buck regulation and supply isolation etc.
