LP3470A:How many /RESET signal level?

Takeshi Satoh
Part Number: LP3470A

The VOL is specified, but I don't understand it.

How many the VOH is it?

If it is not specified as a TTL level, please let me know the FET on-resistance and VDS specifications.

    Hi Takeshi,

    The VOL, Voltage output low, is the voltage value of the RESET pin that is designated as LOW. So in application, since this device is active LOW, the RESET pin will read 0V to 200mV when the RESET asserts. For the VOH, voltage output high, since this device is an open drain, the HIGH value is dependent on the pull-up resistor and the pull up voltage value. For example if you have a 10kohm pull up resistor and the pull up voltage to VDD, the VOH is the VDD. The typical, min and max value of the VOH is going to be dependent on the pull-up resistor value.

    I think VOL is below 200mV when IOUT is below 2mA.
    Even if IOUT is greater than 2mA, will it be less than 200mV?
    Does VDD mean Vcc?

    Hi Takeshi,

    200mV is the highest value of the RESET pin that is in a LOW state. Yes VDD and equivalent to VCC.
