LM7906

The LM7906 is designed as three-terminal negative regulator which is available in TO-220 package and with several fixed output voltages, making it useful in a wide range of applications. It employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible.

LM7906 has five features. (1)Output current in excess of 1A. (2)Output voltages of -6V. (3)Internal thermal overload protection. (4)Short circuit protection. (5)Output transistor safe-area compensation. Those are all the main features.

Some absolute maximum ratings of LM7906 have been concluded into several points as follow. (1)Its input voltage would be -35V. (2)Its thermal resistance junction-cases would be 5°C/W. (3)Its thermal resistance junction-air would be 65°C/W. (4)Its operating temperature range would be from 0°C to 125°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 LM7906 are concluded as follow. (1)Its output voltage would be min -5.75V and typ -6V and max -6.25V. (2)Its line regulation would be typ 10mV and max 120mV with conditions of Vi=-8V to -25V and would be typ 5mV and max 60mV with conditions of Vi=-9V to -12V. (3)Its load regulation would be typ 10mV and max 120mV with conditions of Io=5mA to 1.5A and would be typ 3mV and max 60mV with conditions of Io=250mA to 750mA. (4)Its quiescent current would be typ 3mA and max 6mA. (5)Its quiescent current charge would be max 0.5mA with conditions of Io=5mA to 1A and would be max 1.3mA with conditions of Vi=-9V to -25V. (6)Its temperature coefficient of Vd would be typ =0.5mV/°C. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
