TLV3501A-Q1: Minimum Iq value

FRM
Prodigy 305 points
Part Number: TLV3501A-Q1


Dear support,

on the datasheet of the TLV3501A-Q1 it is shown typical and maximum value of operating Iq 3.2 and 5 mA. However, my customer would need to know the minimum value. Can you please let me know? Thank you & regards, Fernando

    Hello Fernando,

    Unpublished distribution data usually requires an NDA to disclose.

    Minimum supply current is generally not specified for these devices.

    What is their supply voltage? And is that over temp or just room?

    Hello Paul
    the supply voltage is 3.3V , i need to know the quiescent current at 25°C from -40 to 70°C , and Maximum Supply Current from -40°c to 115°C . In the datasheet isn't indicate the variation range of current supply Vs Temperature

    Regards

    Hello Noureddine,

    Quiescent current is the same as Supply current for this datasheet. Why do you have two temperature ranges?

    The TLV3501-Q1 was characterized at -40, 25 and 125°C at 2.7 and 5V. 3.3V numbers would need to be interpolated.

    Figure 12 Quiescent Current vs Temperature graph shows the change in supply current over temperature. It looks to be changing at a slope of +8uA per °C.

    Figure 11. Quiescent Current vs Supply Voltage shows the supply current is changing 100uA between 3 and 5V, or +50uA per volt.

    If we use the 5V numbers, the typical 3.3V supply current would be: 3.2mA - ((5V-3.3V)*50uA) = 3.12mA at 3.3V at 25°C.

    Highest supply current is at hot, so 3.12mA +((115-25)*8uA) = 3.12mA + 720uA = 3.84mA at 115°C at 3.3V.

    So you can see the 3.3V numbers are not too far off from the 5V numbers. So the 5V numbers could be used as a worst case.
