Part Details:

LM137/LM337 November 2004 LM137/LM3373-Terminal Adjustable Negative Regulators 3-T General Description n Excellent thermal regulation, 0.002%/W n 77 dB ripple rejection erminal The LM137/LM337 are adjustable 3-terminal negative volt- n Excellent rejection of thermal transients age regulators capable of supplying in excess of -1.5A overan output voltage range of -1.2V to -37V. These regulators n 50 ppm/°C temperature coefficient are exceptionally easy to apply, requiring only 2 external n Temperature-independent current limit resistors to set the output voltage and 1 output capacitor for n Internal thermal overload protection frequency compensation. The circuit design has been opti- n P+ Product Enhancement tested Adjustable mized for excellent regulation and low thermal transients. n Standard 3-lead transistor package Further, the LM137 series features internal current limiting, n Output is short circuit protected thermal shutdown and safe-area compensation, makingthem virtually blowout-proof against overloads. LM137 Series Packages and Power Capability The LM137/LM337 serve a wide variety of applications in-cluding local on-card regulation, programmable-output volt- Rated Design age regulation or precision current regulation. The LM137/ Device Package Power Load LM337 are ideal complements to the LM117/LM317 Negative adjustable positive regulators. Dissipation Current LM137/337 TO-3 (K) 20W 1.5A Features TO-39 (H) 2W 0.5A n Output voltage adjustable from -1.2V to -37V LM337 TO-220 (T) 15W 1.5A n 1.5A output current guaranteed, -55°C to +150°C LM337 SOT-223 2W
