Pololu 3.3V Step-Up Voltage Regulator U1V10F3 - Tiny Footprint electrolytic capacitor This microswitch has a smallThis 3. 3V 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 3. 3 V electronics projects from 1 to 3 NiMH, NiCd, or alkaline cells or from a single lithium ion cell. When boosting, this module acts as a switching regulator (also called switched mode power
