This 3.3 V boost (step-up) voltage regulator generates higher output voltages from input voltages up to 0.5 V and automatically switches to a linear downshift mode when the input voltage exceeds the output. This makes it ideal for powering 3.3V electronic 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 known as a switching power supply (SMPS) or DC/DC converter) and has a typical efficiency between 65% and 85%. The available output current is a function of the input voltage, output voltage and efficiency (see Typical Efficiency and Output Current section below), but the input current can typically be up to 1.2A. This regulator is also available with a fixed 5V output, and very similar 3.3V, 5V and 5V adjustable output versions are available with a true shutdown option that cuts off the power supply to the load.
Input voltage: 0.5 V to 5.5 V
Fixed 3.3 V output with 4% accuracy
Automatic linear downshift control when the input voltage is greater than the output voltage.
1.2 A switch allows input power up to 1.2 A.
Good efficiency at low load: <1 mA typical no-load quiescent current, although it can exceed 1 mA at very low input voltages.
Small size&scale: 9 × 11.5 × 2.5 mm
