POLOLU 2861 Step Voltage Regulator D24V22F9 9V 2.3A
( Brand: Pololu ), ( Manufacturer Part Number: 2861 ), ( Part Type: Voltage Regulator )
Review POLOLU 9v 2.3a Step Voltage Regulator
The Pololu D24V22F9 9V 2.3A step-down voltage regulator (also known as a buck regulator or switching regulator) is a compact and efficient solution for reducing a higher voltage to a lower voltage. This specific model is designed to step down voltages from as high as 28V to a regulated 9V output.
The regulator is based on the Texas Instruments TPS22917 buck converter, which is known for its high efficiency and low quiescent current. It can provide up to 2.3 amps of continuous output current, making it suitable for powering various low-voltage electronic devices.
The D24V22F9 is a simple-to-use, adjustment-free design. It features a fixed 9V output voltage, making it ideal for applications where a consistent output voltage is required. The regulator also comes with over-current protection, which automatically shuts off the power if the output current exceeds the maximum rating.
The regulator measures 0.7 x 0.8 inches (18.3 x 20.3 mm), making it a compact size suitable for most projects. It also features a thermal shutdown mechanism that turns off the power if the regulator gets too hot, protecting against overheating.
The input voltage can range from 7V to 28V, and the regulator has a typical efficiency of around 85% to 90%, depending on the load conditions. The minimum load for this regulator is around 150mA, and the output voltage can drop by around 0.1V when the load is below this value.
The regulator comes with a screw terminal for easy wiring, and it also includes a 1" x 1" heat sink pad for improved thermal performance. The regulator's compact size, high efficiency, and adjustment-free design make it an excellent choice for powering low-voltage electronic projects.
The Pololu D24V22F9 9V 2.3A step-down voltage regulator (Part Number: 2861) is a linear voltage regulator designed to regulate output voltage despite fluctuations in input voltage. Here are some pros and cons that may help you make an informed decision about purchasing this regulator.
Pros:1. Wide Input Voltage Range: This regulator can handle an input voltage range of 9V to 36V, making it suitable for various power sources.
2. Adjustable Output Voltage: The output voltage can be adjusted using external potentiometer or fixed resistors, providing greater flexibility.
3. Low Dropout Voltage: With a dropout voltage of approximately 0.5V, it can maintain its output voltage even when the input voltage is slightly lower than the desired value.
4. Compact Size: Measuring 0.7 x 0.9 inches, it is relatively small and can easily fit into most projects.
5. Protection Features: It includes thermal shutdown protection and is short-circuit proof, ensuring safe operation.
Cons:1. Linear Regulator: As a linear regulator, it generates heat while operating, which may be a concern for some applications.
2. External Voltage Adjustment: The regulator requires an external potentiometer or fixed resistors to adjust the output voltage, which may add to the complexity of the project.
3. Limited Current Capacity: With a maximum continuous output current of 2.3A, it may not be suitable for high power applications.
In conclusion, the Pololu D24V22F9 9V 2.3A step-down voltage regulator (Part Number: 2861) is a versatile and efficient option for regulating voltage in projects with a wide input voltage range. Its adjustable output voltage, low dropout voltage, and protection features make it a valuable addition to many circuits. However, its linear design, external voltage adjustment, and limited current capacity are factors to consider before making a purchase.
If you are looking for a regulator that can handle high currents or wants a more straightforward voltage regulation solution, you may want to consider other options. However, for projects requiring precise voltage regulation and the ability to handle a wide input voltage range, this regulator is a solid choice.
