Thermal Resistance
TO-252 package                                 JA= 80°C/W
SOT-223 package                               JA= 90°C/W*

* With package soldering to copper area over backside ground plane or internal power plane JA can vary from 46°C/W to >90°C/W depending on mounting technique and the size of the copper area.

The BM1117 series of adjustable and fixed voltage regulators are designed to provide 1A output current and to  perate 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 of BM1117 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.
