Volt Regulator 5V or 3.3V@7A Input 4.5-24V


These buck (step-down) voltage regulators from Pololu generate lower, user-selectable output voltages from an input voltage range of 4.5 to 24 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical (when the output current is several amps) efficiency of approximately 90%, which is much more efficient than linear voltage regulators especially when the difference between the input and output voltage is large. The output voltage defaults to 5 V and can be changed to 3.3 V by jumping 3V3 SELECT. The regulator has under-voltage and short-circuit protection, and thermal shutdown prevents damage from overheating. The board has reverse-voltage protection.
