(1.0A Series)
Semiconductor
http:// www.auk.co.kr
Description
The S52Dxxx 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 S52Dxxx has various key features such as current limiting,
over temperature shut-down, over voltage protection, enable pin, and
low noise performance with an low noise option.
Furthermore, it is available in adjustable or fixed output voltages in SOP-8,
TO-252-5L, TO-220F-4SL packages.

Note 1 : No Heat-sink
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, T
J(max)
,
the junction-to-ambient thermal resistance,
θ
JA
, and the ambient temperature, TA.
The maximum allowable power dissipation at any ambient temperature is calculated using:
PD(max) = (T
J(max)
– T
A
) ÷
θ
JA
. Exceeding the maximum allowable power dissipation will result in
excessive die temperature, and the regulator will go into thermal shutdown.
