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 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 TO252-2 small plastic package.
