Continuous Reset generated by LDO to Microcontroller
What is the reason? Like the time period and the delay are set by the capacitors C2704 and C2703. Without that also, how is the LDO generating a RESET? Can someone please explain.


The output voltage is lower than 6% below reference (Vo_ref) 5 Volt in this case.
The low time period has a guaranteed minimum, either you are overloading the output or the input/output is unstable.

Or you're having a fight with the watchdog.


  And, what should I do to make the RESET line high so that I can program my microcontroller through the debugger?


Fix the regulator operation. Or remove R2704.



For production, add the option to feed the wdt with your programmer. Inhibit reset to your MCU, or make a bootloader image to flash within the watchdog time.
