Other Parts Discussed in Thread: TMP103,
Hi Team,
My customer is mis-using the device as low Iq voltage source. They don't want to add a new device at this late stage in the design.
How is the current limited and to what level (max)?
The DS implies Isc being typ 35mA and Abs max mentions 180mA. As there is drop-out there is also a 'restriction', at 5mA at -40dgC to 85dgC Vdo=135mVtyp which implies an impedance/resistance of 27 Ohms.
Reason is the REF supplies the external TMP103 sensor which is located outside of the PCB or box, This might get shorted and they don't want to damage the REF3330. Which is supplied by 3V3.
