Dynamic load stability is specified for output loads from 10% to 100%. 2. Measured at an internal IC junction. 3. Quiescent current is specified at 0% load for Vin = min to max. 4. This regulator is not designed to be used in parallel with another unit to increase output power. 5. The input should not exceed the range given in the model selection chart above. Exceeding this limit could damage the unit. Derating Curve Notes: 1. C1 is a low ESR ceramic capacitor used to minimize noise at the regulator. A tantalum or low ESR electrolytic capacitor may also be used. A typical value is 22 µF/50V. C1 should be placed as close to pins 1 and 2 as possible. 2. C2 is optional. A typical value is a 100 µF/25V electrolytic capacitor. Mechanical Dimensions Pin Connect.
