D30V33MAx Fine-Adjust Voltage Regulators
The D30V33MAx family of buck (step-down) voltage regulators are larger, adjustable-output members of the larger D30V3x line of synchronous regulators that have through-holes for both 0.1″ headers and for 3.5mm-pitch terminal blocks.
They generate lower output voltages from input voltages as high as 45 V and can typically support continuous output currents between 1.3 A and 4.3 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.

Pololu item #: 4854 | |
Brand: Pololu | supply outlook |
Status: Active and Preferred | |
Output voltage range | Typical max current output1 | Input voltage range2 | Low-voltage cutoff |
---|---|---|---|
4.2 V – 15 V | 3.3 A | 4.2 V – 45 V | adjustable |
1 Typical continuous output current at 30 V in and 9 V out. Actual achievable continuous output current is a function of input and output voltages and is limited by thermal dissipation. See the output current graph on the product page for more information.
2 Input voltage must be higher than the output voltage and is subject to dropout voltage considerations; see the dropout voltage section of product pages for more information.
