Semiconductor
http:// www.auk.co.kr
Description
The S78Dxxx is an efficient linear low dropout voltage regulator for
various electronic equipment. It is designed to provide very low dropout
voltage, and better than 2.4% output voltage accuracy.
And the S78Dxxx has various key features such as current limiting,
over temperature shut-down, over voltage protection, and low noise
performance with an low noise option.
SOT-223
Furthermore, it is available in adjustable or fixed output voltages in
SOT-223, TO-252-3L and TO-220F-3L packages.
