9V Step-Up/Step-Down Voltage Regulator S8V9F9

Pololu's 9V Step-Up/Step-Down Voltage Regulator S8V9F9 is a highly efficient synchronous switching regulator that offers an output of 9V from input voltages ranging from 1.4V to 16V. This dynamic feature makes it an ideal choice for applications where the power supply voltage can fluctuate significantly, such as with batteries that start above but discharge below 9V. The regulator's output current availability is dependent on the input voltage, typically providing around 1A continuous for input voltages close to the output. This voltage regulator is compact in size, measuring only 10.16mm x 16.51mm, and boasts a typical efficiency of 80% to 90%. It also comes with an optional enable input that can be utilized to put the regulator into a low-power state, drawing less than 15µA per volt on VIN, making it a power-efficient solution for your voltage regulation needs.One of the unique properties of this voltage regulator is its ability to operate at a minimum startup voltage of 2.7V, and continue operating down to 1.4V. This makes it highly versatile and suitable for a wide range of applications. Its compact size, high efficiency, and low-power state option make it a practical choice for projects where space and power efficiency are crucial. In conclusion, Pololu's 9V Step-Up/Step-Down Voltage Regulator S8V9F9 is a compact, efficient, and versatile solution for managing voltage in a variety of applications. Its ability to handle both higher and lower input voltages, coupled with its power-efficient design, makes it a standout choice in its category.
