8 / 8 page S5JGS1581D / S5JGS1581D-25 5-Terminal Dual Input Dropout Regulators Elektronische Bauelemente 20-Dec-2011 Rev. A Page 8 of 8 http://www.SeCoSGmbH.com/ Any changes of specification will not be informed individually. PROTECTION DIODES In normal operation S5JGS1581D family does not need any protection diodes between the adjustment pin and the output to the input to prevent die overstresses. Internal resistors are limiting the internal current paths on the ADJ pin. Therefore even with bypass capacitors on the adjust pin no protection diode is needed to ensure device safety under short-circuit conditions. S5JGS1581D The adjust pin can be driver on a transient basis ±7V with respect to the output with out any device degradation. A protection diode between the VOUT pin and VPOWER pin is not usually needed. Microsecond surge currents of 50A ~ 100A can be handled by the internal diode between the Output pin and VPOWER pin of the device. In normal operations it is difficult to get those values of surge currents even with the use of large output capacitance. Only with high value output capacitors, such as 1000µF ~ 5000µF and the VPOWER pin are instantaneously shorted to ground, damage can occur. A diode from output to input is recommended (Figure5). If S5JGS1581D is connected as a single supply device with the control and power input pins shorted together the internal diode between the output and the power input pin will protect the control input pin. |
