IMP1117

The IMP1117 has six key features.The first one is low dropout voltage.The second one is load regulation:0.05% typical.The third one is optimized for low voltage.The fourth one is on-chip thermal limiting.The fifth one is standard SOT-223,TO-220,and TO-252 packages.The sixth one is three-terminal adjustable or fixed low dropout 1.8V,2.5V,2.85V,3.3V,5V.regulators.

The IMP1117A and 1117A-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 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.On-chip thermal limiting provides protection against any combination of overload and ambient temperatures that would create excessive junction temperatures.Unlike PNP type regulators up to 10% of the output current is wasted as quiescent current,the quescent current of the IMP1117A flows into the load,increasing efficiency.The IMP1117A series regulators are available in the industry-standard SOT-223,TO-220,and TO-252(DPAK) power packages.

The IMP1117 has some absolute maximum ratings.When parameter is VIN,the Max.is 18,the unit of IMP1117 is V.When parameter is operating junction temperature range,the Min. is 0,the Max. is 125,the unit is .When parameter is storage temperature range,the Min. is -65,the Max. is 150,the unit is .When parameter is lead temperature (soldering,10 sec.),the Max. is 300,the unit is .
