LMZ12002EXT: Compatibility enable pin with LMZ12002TZ-ADJ

Filip Switakowski

Part Number: LMZ12002EXT

Is LMZ12002EXT fully compatible with LMZ12002TZ-ADJ? I've noticed that datasheet of LMZ12002TZ-ADJ says "The EN pin is internally pulled up to VIN and can be left floating for always-on operation."

I don't see that in LMX12002EXT, so my question is: Can Enable pin of LMX12002EXT be feft floating?

Hi Filip,

For LMZ12002EXT, we don't recommend EN pin floating for always-on operation due to extended operating junction temperature to -55C. Please follow the datasheet to use resistor divider for EN reliable setting.

Hope this helps,

Thanks,

Nancy
