DESCRIPTION
FEATURES
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
•efficiency up to 95%
•1.5A current output
•operating temp: -40 ~ +85°C
•short circuit protection
•thermal shutdown
•low ripple and noise
compact solution. Built-in short-circuit •miniature SIP package,
and over-temperature protections
ensure very rugged operations.
Additionally, low ripple and noise
meets UL94-V0 requirement
•ultra low power loss
•negative output capacity
performance make the parts useful in a •pin compatible to LM78XX series
RoHS
wide range of applications.
•MTBF >2,000,000 hours

1. C1 and C2 are required and should be fitted close to the converter
pins.
2. The capacitance of C1and C2 sees external capacitor table, it can
be increased properly if required, and tantalum or low ESR
electrolytic capacitors may also suffice.
