SC1453

The SC1453 is designed as a low dropout linear regulator that operates from a +2.5V to 6.5V input range and delivers up to 150mA. A PMOS pass transistor allows the low 75uA supply current to remain independent of load, making these devices ideal for battery operated portable equipment such as cellular phones, cordless phones and personal digital assistants.

SC1453 has ten features. (1)"2982/5205" compatible pinout. (2)Guaranteed 150mA output current. (3)Very small external components designed to work with ceramic capacitors. (4)Low 25uVrms output noise. (5)Very low supply current. (6)Thermal overload protection. (7)Reverse battery protection. (8)Low power shutdown. (9)Full industrial temperature range. (10)Surface mount packaging (5 pin SOT-23). Those are all the main features.

Some absolute maximum ratings of SC1453 have been concluded into several points as follow. (1)Its input supply voltage would be from -0.6V to 7V. (2)Its thermal resistance junction to ambient would be 256°C/W. (3)Its thermal resistance junction to case would be 81°C/W. (4)Its operating ambient temperature range would be from -40°C to 85°C. (5)Its storage temperature range would be from -65°C to 150°C. (6)Its lead temperature (soldering) 10 seconds would be 300°C. (7)Its ESD rating 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 SC1453 are concluded as follow. (1)Its supply voltage range would be from 2.25V to 6.5V. (2)Its supply current would be typ 75uA and max 130uA at Io=0mA to 150mA and would be typ 0.1uA and max 1.0uA at Vin=6.5V and Ven=0V. (3)Its output voltage would be min -1.5% and max +1.5%. (4)Its line regulation would be typ 2.5mV and max 10mV. (5)Its load regulation would be typ -5mV and max -20mV. And so on.
