LT3070IUFD-1#PBF

LT3070-1 is a low voltage, UltraFast™ transient response linear regulator. This device supplies upto 5A of output current with a typical dropout voltage of 85mV. This device EN pin controls the reference soft-start behaviour in comparison to the LT3070 which controls the reference soft-start via the BIAS pin supply voltage. This device’s high bandwidth permits the use of low ESR ceramic capacitors, saving bulk capacitance and cost. It 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. It is used in application such as FPGA and DSP supplies, ASIC and microprocessor supplies, servers and storage devices, post buck regulation and supply isolation etc.
