FAN1117AD - Positive Adjustable Voltage Regulator
Description The FAN1117A and FAN1117A- 1.8, -2.5, -2.85, -3.3 and -5 are low dropout three terminal regulators with 1A output current capability. These devices have been optimized for low voltage transient response and minimum input voltage are critical. The 2.85V version is designed for use on SCSI buses in active termination. Current limit adjustment to ensure specified output current and controlled short circuit current. On-chip temperature limiting provides protection against any overload and combined ambient temperature would generate excessive junction temperature. With PNP type regulators as much as 10% of the quiescent current is currently wasted in yield, the quiescent current flows into the load in the FAN1117A, improving efficiency. This series of regulators is available in the FAN1117A in industry standard SOT-223 and TO-252 (DPAK) power packages.
