K7803-500 Datasheet, PDF (1/3 Pages) MORNSUN Science& Technology Ltd. – SINGLE POSITIVE/NEGATIVE OUTPUT

K78XX-500 Series
WIDE INPUT NON-ISOLATED & REGULATED
SINGLE POSITIVE/NEGATIVE OUTPUT
multi-country patent protection RoHS
FEATURES
● Efficiency Up To 96%
●Temperature Range: -40°C to +85°C
● No heat sink Required
● Pin-out compatible with LM78XX Linears
● Short circuit protection, Thermal Shutdown
● Low ripple and noise
● SIP Package
● Industry Standard Pinout
● MTBF>2,000,000 hours
