Pololu 5V Step-Up Voltage Regulator U3V70F5 Offers a true shutdown option that turns off power to the load Operating voltage: 2.9 - 5 V Maximum input current: 10 A Output type: fixed 5V The 5V Step-Up Voltage Regulator U3V70F5 efficiently generates an output voltage of 5 V from an input voltage as low as 2.9 V while using an input current as high as 8 A. This regulator features reverse voltage protection, and unlike most boost regulators, it offers a true shutdown option that turns off power to the load. Features True shutdown option turns off power to the load Typical efficiency of 80% to 95%, depending on input voltage and load (see the Typical efficiencies and output currents section below for performance graphs) Reverse voltage protection Short-circuit protection with hiccup recovery Over-temperature shutoff Under-voltage lockout (typical thresholds are 2.4 V falling, 2.8 V rising) Cycle-by-cycle input current limiting to 10 A Two mounting holes for #2 or M2 screws Smaller holes for 0.1″ header pins and larger holes for terminal blocks offer several options for connecting to the board
