SNVS780D – MAY 1998 – REVISED MAY 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” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not ensure specific performance limits.

(1)

Unless otherwise specified, these specifications apply

−25°C ≤ TJ ≤ + 125°C for the LM337L; |VIN − VOUT| = 5V and IOUT = 40mA.

Although power dissipation is internally limited, these specifications are applicable for power dissipations up to 625 mW. IMAX is 100mA.

(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.

(3)

Thermal resistance of the TO-92 package is 180°C/W junction to ambient with 0.4

″ leads from a PC board and 160°C/W junction to

ambient with 0.125

″ lead length to PC board. The SOIC package θJA is 180°C/W in still air. The 6-Bump DSBGA package θJA is

290°C/W in still air.
