Description

The LM285LP-2-5 is designed as one kind of micropower voltage references. This micropower two-terminal band-gap voltage references operate over a 20uA to 20mA current range and feature exceptionally low dynamic impedance and good temperature stability. On-chip trimming provides tight voltage tolerance. The band-gap reference for these devices has low noise and long-term stability.

LM285LP-2-5 has six features. (1)Operating current range would be 20uA to 20mA. (2)Its 1.5% and 3% initial voltage tolerance. (3)Reference impedance would be 1.5ohms max over full temperature range. (4)Very low power consumption. (5)Applications include portable meter references, portable test instruments, battery-operated systems, current-loop instrumentation and panel meters. (6)Interchangeable with industry-standard. Those are all the main features.

Some absolute maximum ratings of LM285LP-2-5 have been concluded into several points as follow. (1)Its reverse current would be 30mA. (2)Its forward current would be 10mA. (3)Its package thermal impedance would be 140°C/W. (4)Its lead temperature 1.6mm (1/16 inch) from case for 10 seconds would be 260°C. (5)Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of LM285LP-2-5 are concluded as follow. (1)Its reference voltage would be min 2.462V and typ 2.5V and max 2.538V. (2)Its average temperature coefficient of reference voltage would be typ +/-20V. (3)Its change in reference voltage with current would be max 1mV at Iz=20uA to 1mA and would be max 10uA at Iz=1uA to 20mA. (4)Its long term change in reference voltage would be typ +/-20ppm/khr. (5)Its minimum reference current would be typ 8uA and max 20uA. (6)Its reference impedance would be typ 0.2ohms and max 0.6ohms. (7)Its boardband noise voltage would be typ 120uV. And so on.
