DescriptionThe LM137K is one member of the LM137 family.The LM137/LM337 are adjustable 3-terminal negative voltage regulators capable of supplying in excess of -1.5A over an output voltage range of -1.2V to -37V. These regulators are exceptionally easy to apply, requiring only 2 external resistors to set the output voltage and 1 output capacitor for frequency compensation. The circuit design has been optimized for excellent regulation and low thermal transients. Further, the LM137 series features internal current limiting, thermal shutdown and safe-area compensation, making them virtually blowout-proof against overloads.
Features of the LM137K are:(1) Output voltage adjustable from .1.2V to .37V; (2)1.5A output current guaranteed, .55°C to +150°C; (3) Line regulation typically 0.01%/V; (4) Load regulation typically 0.3%; (5) Excellent thermal regulation, 0.002%/W; (6) 77 dB ripple rejection; (7) Excellent rejection of thermal transients; (8) 50 ppm/°C temperature coefficient; (9) Temperature-independent current limit; (10) Internal thermal overload protection; (11) P+ Product Enhancement tested; (12) Standard 3-lead transistor package; (13) Output is short circuit protected.
The absolute maximum ratings of the LM137K can be summarized as:(1)Power Dissipation:Internally Limited;(2)Input-Output Voltage Differential:40V;(3)Operating Junction Temperature Range: -55 to 150°C;(4)Storage Temperature:-65°C to +150°C;(5)Lead Temperature:300°C;(6)Plastic Package (Soldering, 4 sec.): 260°C.
