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 F/50V. 2. C2 is optional. A typical value is a 100 F/25V electrolytic capacitor. Derating Curve Pin Connections Pin 1 2 3 Description +Vin Gnd +Vout Notes: * All dimensions are typical in inches (mm) * Tolerance x.xx = 0.01 (0.25) * Pin 1 is marked by a "dot" or indentation on the side of the unit MicroPower Direct www.micropowerdirect.com * 292 Page Street Ste D Stoughton, MA 02072 TEL: (781) 344-8226 * FAX: (781) 344-8481 * E-Mail: sales@micropowerdirect.com |
