Units MTBF MIL HDBK 217F, 25°C, Gnd Benign 2.0 MHours Series MicroPower Direct 292 Page Street Suite D Stoughton, MA 02072 USA T: (781) 344-8226 F: (781) 344-8481 E: sales@micropowerdirect.com W: www.micropowerdirect.com Notes: 1. C1 & C2 are low ESR ceramic capacitors used to minimize noise at the regulator. A tantalum or low ESR electrolytic capacitor may also be used. 2. C1 & C2 are required and should be mounted as close to the regulator pins as possible. C3 is required for optimum performance, use 100 µF OR more. 3. R1 & R2 are used to adjust the regulator output. For sug- gested values, please contact the factory.
