TLV9002: V+ 1.8V tolerance

Part Number: TLV9002

Hi Team,

Please help to confirm V+(min) 1.8V tolerance.

Our 1.8V have some tolerance, concern may not meet TLV9002 V+ range.

Thanks

    Hi Daniel,

    The supply voltage  recommended operating condition for TLV9002 is between 1.8V to 5.5V. If your tolerance makes you go beyond this operating condition, the device may show some abnormal behavior. But, since you're within the absolute max rating, you won't damage your device. 

    Best Regards,

    Hi Bala,

    Currently the V+ source design for TLV9002S from our system is 1.8V (+/-1.5% tolerance).

    if it's OK range for TLV9002S, or in other words does TLV9002S can support 1.8V power source?

    Thanks

    Daniel,

    -1.5% of 1.8V is just -27mV for a Vs of 1.773V

    The device is tested and characterized at 1.8V and the device is typically functional well below 1.8V

    I consider the added risk you must assume for using 1.773V (absolute minimum) as negligible.
