... This performance is thus well inside the specification limit of 0.2%/ 0.2% maxi- mum. When the 1W pulse is ended, the thermal regulation again shows change as the gradients across the LM317L chip die out. Note that the load regulation error of about 14 mV (0.14%) is additional to the thermal regulation error ...

... Internal to the LM317L current. No protection is needed for output voltages of 25V or less and 10µF capacitance. Figure 3 shows an LM317L with protection diodes included for use with outputs greater than 25V and high values of output capacitance. FIGURE 3. Regulator with Protection Diodes micro SMD does not sustain permanent damage from light exposure. Removing the light source will cause LM317L’ ...
