Description
5V Positive Voltage Regulator (Preliminary) Description The SE78L05D is three-terminal positive regulator. The SE78L05D 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. SE78L05D Features Output voltage of 5.0V (Typ.) Output current up to 150mA (Typ.) Minimum external components. Output voltage tolerances of ±4% ESD rating is 3KV (Per MIL-STD-883D). Application Sound card on PC main board. DVD-ROM, CD-ROM. Networking Equipments.
