Product FAQs

What is a reverse current protection circuit in NJM12884?
Please tell me where a specification value of this reverse current protection is mentioned in the data sheet.


This protection circuit prevents NJM12884 from flowing the large reverse current when output voltage is higher than input voltage. Therefore, an external schottky-barrier diode(SBD) is not required to connect it.
The operating range of protection circuit is mentioned to an output voltage column of maximum ratings.
