The Pololu 5V, 3.2A Step-Down Voltage Regulator is a synchronous switching step-down (or buck) regulator that takes an input voltage of up to 50V and efficiently reduces it to 5V.Note: (Insert any product notes here in Red BOLD Italic. Example: "First Shipment expected January 2022" or "Electronics are Not Included".)VIDEO: (Insert Video Title here in Bold)FeaturesPower-save mode with ultrasonic operation that increases light load efficiency by reducing switching frequency, but keeps it above the audible range (20 kHz)Available output current is a little higher for the lower-voltage versions than it is for the higher-voltage versions, and it decreases as the input voltage increasesIntegrated reverse-voltage protection up to 40 V, over-current and short-circuit protection, over-temperature shutoffSupports continuous output currents between 2 A and 4 A, depending on the input voltage and output voltage"Power good" output indicates when the regulator cannot adequately maintain the output voltageSwitching regulator makes the regulator much more efficient than linear voltage regulatorsSoft-start feature limits inrush current and gradually ramps output voltageLower output voltages from input voltages as high as 50 VOutput undervoltage and overvoltage protectionTwo 0.086″ mounting holes for #2 or M2 screws2 mA to 3 mA typical no-load quiescent currentCompact sizeCONNECTIONSThis regulator has six connections: power good (PG), enable (EN), input voltage (VIN), output voltage (VOUT), and two ground (GND) connections.The "power good" indicator, PG, is an open-drain output that goes low when the regulator's output voltage either rises more than 20% above or falls more than 10% below the nominal voltage (with hysteresis). An external pull-up resistor is required to use this pin.The regulator, which is enabled by default, can be put into a low-power sleep state by reducing the voltage on the EN pin below 1.2 V, and it can be brought out of this state again by increasing the vol
