STM32F030 High current in stop mode

I would like to put STM32F030K6T6 into STOP mode (low power mode), in which there should be current consumption around 5 μA.

But whatever I do the current consumption is around 450 μA in stop mode.

There is basically nothing else on the PCB, it's as simple as possible.

The board without MCU consumes 7 μA, that is quiescent current of LDO. So in the end I would expect to get 12 μA (7 + 5 μA).

When I place there MCU the consumption is around 2-3 mA in normal mode and 450 μA in stop mode.

All pins are set to analog input with no pull-ups, which is recommended config. All peripherals are disabled (like ADC, IWDG, I2C, SPI, timer, etc.). Only RTC is enabled.

I tried it with all pins set to output, it did not help either.

What do I do wrong?
