Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
1. Tlow to Thigh = 0° to +125°C, for LM337T, D2T. Tlow to Thigh = − 40° to +125°C, for LM337BT, BD2T.
2. Imax = 1.5 A, Pmax = 20 W
3. Load and line regulation are specified at constant junction temperature. Change in VO because of heating effects is covered under the
Thermal Regulation specification. Pulse testing with a low duty cycle is used.
4. CAdj, when used, is connected between the adjustment pin and ground.
5. Power dissipation within an IC voltage regulator produces a temperature gradient on the die, affecting individual IC components on the die.
These effects can be minimized by proper integrated circuit design and layout techniques. Thermal Regulation is the effect of these
temperature gradients on the output voltage and is expressed in percentage of output change per watt of power change in a specified time.
6. Since Long Term Stability cannot be measured on each device before shipment, this specification is an engineering estimate of average
stability from lot to lot.
