K7803-1000 Datasheet, PDF (1/3 Pages) MORNSUN Science& Technology Ltd. – SINGLE POSITIVE /NEGATIVE OUTPUT
K78XX-1000 Series
WIDE INPUT NON-ISOLATED & REGULATED
SINGLE POSITIVE /NEGATIVE OUTPUT
multi-country patent protection RoHS
FEATURES
● Efficiency up to 96%
● Operating temperature: -40°C to +85°C
● Pin-out compatible with LM78XX Linear
● Short circuit protection, thermal Shutdown
● Low ripple and noise
● Micro miniature SIP package
● No heat sink required
● Industry standard pinout
● MTBF>2,000,000 hours
● Can be used to convert a positive voltage
into a negative voltage
● Only two extra capacitors are required
● Input voltage range can be lower than the
output voltage for higher output voltages
in negative application
APPLICATIONS
The K78xx-1000 Series high efficiency
switching regulators are ideally suited to replace
78xx linear regulators and are pin compatible.
The efficiency of up to 96% means that very little
energy is wasted as heat so there is no need for
any heat sinks with their additional space and
mounting costs.
