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.

Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical
specifications do not apply when operating the device outside of its operating ratings. The maximum
allowable power dissipation is a function of the maximum junction temperature, TJ(max) ,
the junction-to-ambient thermal resistance, θJA, and the ambient temperature, TA.
The maximum allowable power dissipation at any ambient temperature is calculated using:
PD(max) = (TJ(max) – TA) ÷ θJA. Exceeding the maximum allowable power dissipation will result in
excessive die temperature, and the regulator will go into thermal shutdown.
