Description

The LM237KC is designed as one kind of adjustable 3-terminal negative-voltage regulators capable of supplying in excess of -1.5A over an output voltage range of -1.2V to -37V. It is exceptionally easy to use, requiring only two external resistors to set the output voltage and one output capacitor for frequency compensation.

LM237KC has seven features. (1)Output voltage range adjustable from -1.2V to -37V. (2)Output current capability of 1.5A max. (3)Input regulation typically 0.01% per input-voltage change. (4)Output regulation typically 0.3%. (5)Peak output current constant over temperature range of regulator. (6)Ripple rejection typically 77dB. (7)Direct replacement for industry-standard LM237 and LM337. Those are all the main features.

Some absolute maximum ratings of LM237KC have been concluded into several points as follow. (1)Its input to output differential voltage would be -40V. (2)Its operating virtual junction temperature would be 150°C. (3)Its lead temperature 1.6mm (1/16inch) from case for 10 seconds would be 260°C. (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 LM237KC are concluded as follow. (1)Its input regulation would be typ 0.01%/V and max 0.02%/V. (2)Its ripple rejection would be typ 60dB. (3)Its output regulation would be max 25mV at Vo<=5V. (4)Its output voltage change with temperature would be typ 0.6%. (5)Its output voltage long-term drift would be typ 0.3% and max 1%. (6)Its output noise voltage would be typ 0.003%. (7)Its minimum output current to maintain regulation would be typ 2.5mA and max 5mA. (8)Its peak output current would be min 1.5A and typ 2.2A. (9)Its adjustment-terminal current would be typ 65uA and max 100uA. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
