For value given, capacitor must be solid tantalum. 25 mF aluminum electrolytic may be substituted. ²Required for stability. For value given, capacitor must be solid tantalum. 25 mF aluminum electrolytic may substituted. Values given may be increased without limit. For output capacitance in excess of 100 mF, a high current diode from input to output (1N4001, etc.) will protect the regulator from momentary input shorts.

Note 2: Regulation is measured at constant junction temperature. Changes in output voltage due to heating effects must be taken into account separately. To ensure constant junction temperature, low duty cycle, pulse testing is used. The LM120/LM320 series does have low thermal feedback, improving line and load regulation. On all other tests, even though power dissipation is internally limited, electrical specifications apply only up to P D. Note 3: For b5V 3 amp regulators, see LM145 data sheet.
