NOTES: 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. 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.
6. 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.
