Compact design at 0.6″ × 1.0″ dimensions
The Pololu 1.4-7V, 3.4A Fine-Adjust Step-Down Voltage Regulator D30V30MAL is a high-efficiency voltage regulator with an adjustable output range from 1.4 V to 7 V and a maximum continuous output current of 3.4 A. It operates within an input voltage range of 3 V to 45 V and features a precision-adjustable output via an 11-turn potentiometer. The regulator is designed for optimal performance with low dropout voltage, a power-save mode for light load efficiency, and a low quiescent current. It includes protections such as under-voltage lockout, reverse-voltage protection, over-current and short-circuit protection, and over-temperature shutoff.
