Dynamic load stability is specified for output loads from 10% to 100%. 2. Quiescent current is specified at 0% load for Vin = min to max. 3. The input should not exceed the range given in the model selection chart above. Exceeding this limit could damage the unit. Mechanical Dimensions Typical Application Circuit 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 10 µF/50V. 2. C2 is optional. A typical value is a 100 µF/25V electrolytic capacitor.
