5V Positive Voltage
Regulator (Preliminary)
Features
Output voltage of 5.0V (Typ.)
SE78L05
Description
The SE78L05 is three-terminal positive regulator.
The SE78L05 can be used as Zener diode/resistor
combination replacement. It offers an effective
output impedance improvement of two orders of
magnitude, and lower quiescent current. This fixed
voltage regulators can provide local or on-card
regulation for elimination of noise and distribution
problems associated with single point regulation. It
is an excellent solution to the stereo power supply
on PC main board.
Output current up to 150mA (Typ.)
Minimum external components.
Output voltage tolerances of 鹵4%
ESD rating is 2.7KV (Per MIL-STD-883D).
Application
Sound card on PC main board.
DVD-ROM, CD-ROM.
Networking Equipments.
