Pololu 5V Step-Up Voltage Regulator U1V11F5 - Ultra-Compact e18-d80nk relays & DC motors toThis 5 V boost (step up) voltage regulator generates higher output voltages from input voltages as low as 0. 5 V, and it also automatically switches to a linear down regulation mode when the input voltage exceeds the output. This makes it great for powering 5 V electronics projects from 1 to 3 NiMH, NiCd, or alkaline cells or from a single lithium ion cell. Additionally, unlike most boost regulators, this unit offers a true shutdown option that turns
