D24V25Fx Step-Down Voltage Regulators
These compact synchronous, switching step-down voltage regulators generate lower output voltages from input voltages as high as 38 V. They offer typical efficiencies of 80% to 95% and continuous output currents up to 2.5 A.
The modules have built-in reverse-voltage protection, short-circuit protection, a thermal shutdown feature that helps prevent damage from overheating, and a soft-start feature that reduces inrush current.

Note: For newer, lower-priced step-down regulators with a similar input voltage range, output current, and size, consider the D24V22Fx family of regulators. Please note that while these D24V22Fx regulators look very similar to the D24V25Fx family of regulators, they do not have the same pinout and are based on a different internal design, so there are fundamental differences in operation. The D24V22Fx family also includes a 12 V option while the D24V25Fx family does not.
