LM25066I: disablling UVLO and OVLO?

Part Number: LM25066I

Hi there,

is it possible to turn off the UVLO and OVLO, by connecting them respectively with VDD and GND (without additional resistors)?

Thanks!

    Hi Bart,

    Thanks for reaching out to us. UVLO/EN can be connected directly to VDD if input voltage is above 3.3 V and OVLO directly to GND to disable under-voltage and over-voltage functionalities respectively. For input voltages 3.3 V and below, VDD and UVLO/EN should be tied directly to VIN to avoid the dropout of the sub-regulator. External pull-up or pull-down resistors are not required.
