LM385LP-2.5

The LM385LP-2.5 is designed as one kind of micropower voltage references which are two terminal bandgap reference diodes designed and optimized for accurate low power operation in portable and other power sensitive systems.

LM385LP-2.5 has five features. (1)Guaranteed 3% initial accuracy. (2)Guaranteed 20uA operating current. (3)Low temperature coefficient. (4)Operating current of 20uA to 20mA. (5)Very low dynamic impedance 1ohms. Those are all the main features.

Some absolute maximum ratings of LM385LP-2.5 have been concluded into several points as follow. (1)Its reverse breakdown current would be 30mA. (2)Its forward current would be 10mA. (3)Its operating temperature range would be from 0°C to 70°C. (4)Its storage temperature range would be from -65°C to 150°C. (5)Its lead temperature soldering 10 seconds would be 300°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device. All voltages are specified with respect to ground, and all currents are positive into the specified terminal.

Also some electrical characteristics of LM385LP-2.5 are concluded as follow. (1)Its reverse breakdown voltage would be mi 2.462V and typ 2.5V and max 2.538V with conditions of Imin<Ir<Imax. (2)Its average temperature coefficient would be typ 20ppm/°C with conditions of Ir=100uA. (3)Its minimum operating current would be typ 13uA and max 20uA. (4)Its reverse breakdown voltage change with current would be max 2mV at Imin<Ir<1mA and would be max 20mV at 1mA<Ir<20mA. (5)Its reverse dynamic impedance would be typ 1ohms with conditions of Ir=100uA, f=20Hz. (6)Its wide band noise (RMS) would be typ 120uV with conditions of Ir=100uA and 10Hz<f<10KHz. (7)Its long term stability would be typ 20ppm/kHr with conditions of Ir=100uA, Ta=25°C. And so on. At present we have not got so much information about this IC and we would try hard to get more information about it.
