B1117 General Description


The Bay Linear B1117 is a three terminal positive NPN regulator offered as adjustable or fix voltages of 1.5V,1.8V, 2.5V, 2.85V, 3.3V, and 5Volts. The output current has a capability up to 1.0Amp,. This device has been optimized for low voltage where transient response and minimum input voltage are critical. The 2.85V version is designed specifically to be used in active terminators for SCSI bus.

Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-Chip thermal limiting provides protection against any combination of overload and ambient temperatures that would create excessive junction temperatures.

The B1117A is offered in a 3-pin SOT-223, and TO-252 (DPAK) packages compatible with other 3 terminal regulators. 5-pin version in TO-263 with lower dropout of 0.4 volt is available.
