Pololu 9V Step-Up Voltage Regulator U3V50F9 - 2.9V+ Input zippy 1 × QTR-1A Reflectance SensorThese boost (step up) voltage regulators generate higher output voltages from input voltages as low as 2. 9 V. They are switching regulators (also called switched mode power supplies (SMPS) or DC to DC converters) and have a typical efficiency between 80% to 95%. The available output current is a function of the input voltage, output voltage, and efficiency (see the Typical Efficiency and Output Current section below), but the input current can
