Pololu 6V, 2.5A Step-Down Voltage Regulator D24V25F6

The Pololu D24V25Fx family of step-down voltage regulators efficiently converts higher input voltages up to 38V to lower fixed output voltages, with a maximum continuous output current of 2.5A. Featuring efficiencies between 85% and 95%, these compact regulators are ideal for applications where space and power conservation are critical. They include features like reverse-voltage protection, short-circuit protection, thermal shutdown, and a soft-start mechanism, all within a small footprint of 17.8 mm × 17.8 mm × 9 mm.

These regulators are perfect for powering a variety of electronics, from microcontrollers to sensors, in robotics and embedded systems. Their ability to maintain high efficiency even with significant differences between input and output voltages makes them particularly useful in battery-powered devices, where conserving energy is crucial. The automatic adjustment of switching frequency at light loads ensures optimal efficiency across a range of operating conditions.

One of the unique advantages of these regulators is their versatility in handling different input and output voltages with high precision and reliability. The built-in safety features such as thermal shutdown and short-circuit protection provide peace of mind in demanding environments. Additionally, the ENABLE pin allows users to reduce quiescent current to as low as 10 µA to 20 µA per volt on VIN, making it highly energy-efficient when not in use.

With several fixed output voltage options (3.3V, 5V, 6V, 7.5V, and 9V), these regulators can be tailored to meet specific requirements. Their compact design, along with two 2.18 mm mounting holes for easy installation, makes them suitable for a variety of projects where space is limited. For those requiring higher power, Pololu offers larger, pin-compatible versions capable of delivering up to 9A, with additional features like a "power good" signal and adjustable output voltage.

The D24V25Fx regulators are equipped with five connection points, arranged for compatibility with standard prototyping tools such as solderless breadboards. This feature, along with the option to solder directly for a more compact setup, adds to the flexibility and ease of integration into existing systems.

Overall, this family of step-down voltage regulators is designed to offer robust performance, adaptability, and safety, making them a reliable choice for powering a wide range of electronic devices. Whether for hobbyist projects or professional applications, these regulators deliver consistent and efficient power conversion.
