Description
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
This amazing little board really delivers. It can deliver lots of current at 5v from LiPo batteries, for example. The enable pin is super useful to add a switch without having to put the switch inline.
