Typ. Max. Units MTBF MIL HDBK 217F, 25°C, Gnd Benign 2.0 MHours Series Electrical Specifi cations Specifi cations typical @ +25°C, nominal input voltage & rated output current, unless otherwise noted. Specifi cations subject to change without notice.
Notes: 1. Dynamic load stability is specifi ed for output loads from 10% to 100%. 2. Quiescent current is specifi ed 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. 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.
