V7803-1000

a d ivision of CUI INC date 07/2010 page 1 of 5 SERIES: V78XX-1000 DESCRIPTION: DC SWITCHING REGULATOR, NON-ISOLATED DESCRIPTION The V78XX switching regulator series is designed to be a high efficiency drop-in replacement for 78XX linear regulators. Unlike linear regulators, the V78XX series does not require a heatsink, creating a much more compact solution. Built-in short-circuit and over-temperature protections ensure very rugged operations. Additionally, low ripple and noise performance make the parts useful in a wide range of applications. FEATURES •efficiency up to 97% •1A current output •operating temp: -40 ~ +85°C •short circuit protection •thermal shutdown •low ripple and noise •miniature SIP package, meets UL94-V0 requirement •ultra low power loss •negative output capacity •pin compatible to LM78XX series •MTBF >2,000,000 hours RoHS efficiency level Vin (min) Vin (max) MODEL V7803-1000 V7805-1000 V7806-1000 V7809-1000 V7812-1000 V7815-1000 input voltage min (V dc) max (V dc) output voltage max (V dc) output current max.

C1 and C2 are required and should be fitted close to the converter pins. 2. The capacitance of C1, C2, C3 and C4 sees external capacitor table, it can be increased properly if required, and tantalum or low ESR electrolytic capacitors may also suffice. 3. No parallel connection or plug and play.
