Precautions
l
The overcurrent protection function of this IC detects and limits the sink current at the EXT terminal inside the IC.
Therefore, it does not work on collector overcurrents which are caused by an EXT-GND short-circuiting or other
phenomenon outside the IC. To protect the external PNP transistor from collector overcurrents perfectly, it is necessary to
provide another external overcurrent protection circuit.
l
This IC performs phase compensation by using an internal phase compensator circuit and the ESR of an output capacitor.
Therefore, always place a capacitor of 4.7uF or more between V
OUT
and Vss. A tantalum type capacitor is recommended
for this purpose. Moreover, to secure stable operation of the S-816 Series, it will be necessary to employ a capacitor
having an ESR (Equivalent Series Resistance) covered in a certain optimum range (0.1
W
to 5
W
). Whether an ESR is
larger or smaller than that optimum range, this could result in an unstable output, and cause a possibility of oscillations.
Select a capacitor through careful evaluation made according to the actual service conditions.
l
Make sure that the power dissipation inside the IC due to the EXT output sink current (especially at a high temperature)
will not surpass the power dissipation of the package.
