Original question:
Hello,
I am using the LMZ21700 with an output at 6V/50mA.
In these conditions, what is the minimum input voltage to ensure proper operations?
Looking to figure 8 and 9 in the datasheet (doc number SNVS872C) does not help, because Vout is 5V and 3V3 respectively.
Hi Romain,
I took the LMZ21700EVM and did a Vin/Iout sweep similar to Figure 8 and 9. Attached is the dropout bench results for Vout = 6V at room ambient temperature. The minimum input voltage for 6V output should be at least 6.25V for proper regulation.
