LM25066I: disablling UVLO and OVLO?

Expert 6170 points
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)?


  • 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.
