S78Dxxx
Low Dropout Voltage Regulator (1.0A Series)
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.
Furthermore, it is available in adjustable or fixed output voltages in
SOT-223, TO-252-3L and TO-220F-3L packages.
