SERIES:
V78XX-1500
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 95%
•1.5A 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
