3 / 22 page LM137, LM337-N www.ti.com SNVS778D – MAY 1999 – REVISED APRIL 2013 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. ABSOLUTE MAXIMUM RATINGS (1) (2) Power Dissipation Internally Limited Input-Output Voltage Differential 40V Operating Junction Temperature Range LM137 −55°C to +150°C LM337-N 0°C to +125°C LM337I −40°C to +125°C Storage Temperature −65°C to +150°C Lead Temperature (Soldering, 10 sec.) 300°C Plastic Package (Soldering, 4 sec.) 260°C ESD Rating 2k Volts (1) Refer to RETS137H drawing for LM137H or RETS137K drawing for LM137K military specifications. (2) Unless otherwise specified, these specifications apply −55°C ≤ Tj ≤ +150°C for the LM137, 0°C ≤ Tj ≤ +125°C for the LM337-N; VIN − VOUT = 5V; and IOUT = 0.1A for the TO package and IOUT = 0.5A for the TO-3, SOT-223 and TO-220 packages. Although power dissipation is internally limited, these specifications are applicable for power dissipations of 2W for the TO and SOT-223 (see APPLICATION HINTS), and 20W for the TO-3, and TO-220. IMAX is 1.5A for the TO-3, SOT-223 and TO-220 packages, and 0.2A for the TO package.

Although power dissipation is internally limited, these specifications are applicable for power dissipations of 2W for the TO and SOT-223 (see APPLICATION HINTS), and 20W for the TO-3, and TO-220. IMAX is 1.5A for the TO-3, SOT-223 and TO-220 packages, and 0.2A for the TO package. (2) Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating effects are covered under the specification for thermal regulation. Load regulation is measured on the output pin at a point ⅛ in. below the base of the TO-3 and TO packages. (3) Selected devices with tightened tolerance reference voltage available.
