Frequently asked questions

What is the minimum input voltage required for the LNBH23?

The device functions with a single input voltage supply ranging from 8 V to 15 V.

What is the typical output current limit when the ITEST pin is set to 0?

The output current is lower than 6 mA when ITEST=0.

At what junction temperature does the overtemperature flag activate?

The OTF bit is set to "1" if the junction temperature exceeds 150 °C.
