PRODUCTION DATA. LM337-N-MIL SNVSAX3 – JUNE 2017 LM337-N 3-Terminal Adjustable Negative Regulators 1 1 Features 1 • 1.5-A Output Current • Line Regulation 0.01%/V (Typical) • Load Regulation 0.3% (Typical) • 77-dB Ripple Rejection • 50 ppm/°C Temperature Coefficient • Thermal Overload Protection • Internal Short-Circuit Current Limiting Protections 2 Applications • Industrial Power Supplies • Factory Automation Systems • Building Automation Systems • PLC Systems • Instrumentation • IGBT Drive Negative Gate Supplies • Networking • Set-Top Boxes 3 Description The LM337-N-MIL is an adjustable 3-terminal negative voltage regulator capable of supplying −1.5 A or more currents over an output voltage range of −1.25 V to −37 V. It requires only two external resistors to set the output voltage and one output capacitor for frequency compensation. The circuit design has been optimized for excellent regulation and low thermal transients. Further, the LM337-N-MIL features internal current limiting, thermal shutdown and safe-area compensation, making it virtually blowout-proof against overloads. The LM337-N-MIL is an ideal complement to the LM117 and LM317 adjustable positive regulators. Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) LM337-N-MIL SOT-223 (4) 3.50 mm × 6.50 mm TO (3) 8.255 mm × 8.255 mm TO-220 (3) 10.16 mm × 14.986 mm (1) For all available packages, see the orderable addendum at the end of the data sheet. The LF01 is a lead formed (bent) version of the TO-220 package. Adjustable Negative Voltage Regulator Full output current not available at high input-output voltages †C1 = 1-μF solid tantalum or 10-μF aluminum electrolytic required for stability *C2 = 1-μF solid tantalum is required only if regulator is more than 4″ from power-supply filter capacitor Output capacitors in the range of 1-μF to 1000-μF of aluminum or tantalum electrolytic are commonly used to provide improved output impedance and rejection of transients |
