SC1112

The SC1112 is designed as one kind of triple low dropout regulator controllers for the latest high speed motherboards. It includes three low dropout regulator controllers. The controllers provide the power for the system AGTL bus termination voltage, chipset and clock circuitry.

SC1112 has six features. (1)Tripple linear controllers. (2)Selectable and adjustable output voltages. (3)LDOs track input voltage within 200mV (function of the mosfets used) until regulation. (4)Integrated charge pump. (5)Programmable power good delay signal. (6)Latched over current protection (VTT). Those are all the main features.

Some absolute maximum ratings of SC1112 have been concluded into several points as follow. (1)Its 5VSTBY to GND would be from -0.3V to 7V. (2)Its VTTSEN to GND would be form -0.3V to 5V. (3)Its AGPSEN to GND would be from -0.3V to 5V. (4)Its ADJSEN to GND would be from -0.3V to 5V. (5)Its operating temperature range would be from 0°C to 70°C. (6)Its storage temperature range would be from -65°C to 150°C. (7)Its lead temperature soldering 10 seconds would be 300°C. (8)Its thermal resistance junction to ambient would be 130°C/W. (9)Its thermal impedance junction to case would be 30°C/W. (10)Its ESD rating (human body model) would be 2KV. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of SC1112 are concluded as follow. (1)Its supply voltage would be min 4.75V and typ 5V and max 5.25V. (2)Its supply current would be min 6mA and typ 8mA and max 12mA. (3)Its VTT short circuit delay timer threshold would be typ 1.5V. (4)Its VTT short circuit delay source current would be min 16uA and typ 22uA and max 28uA. (5)Its VTT short circuit threshold would be min 650mV and typ 700mV and max 750mV. And so on.
