Part Number:TPS782
Hi all,
I have a TPS78233DDCR with Cin=1uF and Cout = 1uF, both X5R; EN pin always enabled.
When Vin<3.6V, the output voltage is equal to Vin (LDO is in "Operating Mode Droput", page 11 of datasheet). When Vin > 3.6V, the output voltage go to 3.3V but oscillate between 3.3V and 3.35V; if Vin increase, the difference in Vout increase too; for example, when Vin = 4,2V, the 3.3<Vout<3.6 !
The output current is 10uA.
I have 3 boards with this schematic and the situation is the same.
There is any solution?
Thank you,
