K7805T-500 Datasheet, PDF (1/5 Pages) MORNSUN Science& Technology Ltd. – WIDE INPUT, NON-ISOLATED & REGULATED SMD PACKAGE SINGLE OUTPUT

K78XXT-500 Series
WIDE INPUT, NON-ISOLATED & REGULATED
SMD PACKAGE SINGLE OUTPUT
FEATURES
● Efficiency up to 96%
● No need for heat sinks
● 0.5AMP SMD package
● Wide input voltage range(4.5V~28V)
● Adjustable output voltage
● Remote ON/OFF control
●Short circuit protection, Thermal shutdown
● Very low shutdown current
● Super low ripple and noise
APPLICATIONS
The K78xxT-500 Series with high efficiency
switching regulators are ideally supply for space
constrained mobile applications. They are no
need for any heat sinks, even if operate at
+85°C. The additional features include remote
ON/OFF control and adjustable output voltage.
Super low ripple and noise of typically only
10mV and a shutdown input current of typically
only 15uA.
