Description

The BM1117 series of adjustable and fixed voltage regulators are designed to provide 1A output current and to operate down to 1V input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.3V at maximum output current, decreasing at lower load currents. On-chip trimming adjusts the reference voltage to within 1% accuray. Current limit is also trimmed, minimizing the stress under overload conditions on both the regulator and power source circuitry. The BM1117 devices are pin compatible with other three-terminal SCSI regulators and are offered in the low profile surface mount SOT-223 package and in the TO-252 (DPAK) plastic package.

A synchronous buck regulator, often simply called a “synchronous buck converter,” is a type of switching voltage regulator used to step down a higher input voltage to a lower output voltage efficiently. It’s a variation of the basic step-down or buck regulator that incorporates synchronous rectification to improve overall efficiency.

Description

The Z1051PI is a high efficiency, easy to use, 3 A synchronous buck regulator. The AOZ1051PI works from 4.5 V to 18 V input voltage range, and provides up to 3 A of continuous output current with an output voltage adjustable down to 0.8 V.

A synchronous buck regulator is a type of DC-DC (direct current to direct current) power converter that is commonly used to step down a higher voltage input to a lower voltage output.

The synchronous buck regulator is known for its high efficiency, due in part to the synchronous switching technology that minimizes power losses. It is widely used in electronic devices such as computers, smartphones, and other battery-powered applications where efficient power conversion is critical.
