Product Number: MAX42402
Hi,
the buck regulator MAX42402 includes an internal LDO that powers the BIAS voltage (1.8V). Even though the datasheet shows that this voltage can be used to supply the pull-up connected to the open-drain PGOOD output, the maximum current that may be drawn from the BIAS supply is not specified.
Is it allowed to use the BIAS voltage for more peripheral circuitry? In my application I'd like to power a small TinyLogic buffer with it (several µA of static current needed, max. below 0.5mA).
Is this approach feasible or is not advised to load the BIAS supply externally with more than the shown 20k pull-up?
Best regards,
Thomas
