The D30V30MAx family of buck (step-down) voltage regulators are compact, adjustable-output members of the broader D30V3x line of synchronous regulators. They generate lower output voltages from input voltages as high as 45 V and can typically support continuous output currents between 1 A and 4 A, depending on the input voltage and output voltage. They also have very low dropout voltages.

The output voltage is precision adjustable through an 11-turn potentiometer, and each version is available with or without an adjustable low-voltage cutoff (also set through a precision 11-turn potentiometer).
The regulators have reverse voltage protection up to 40 V, input under-voltage lockout, over-current protection, and short-circuit protection. A thermal shutdown feature also helps prevent damage from overheating and a soft-start feature limits the inrush current and gradually ramps the output voltage on startup.
