1. The LDO18 is a built in low dropout voltage regulator, which can be used if the host system does not provide the core volt-
2. The LDOBAT is a built in low dropout voltage regulator, which provides the supply voltage VBAT18 for the RTC, backup
3. Supply voltage VBAT18 for backup domain is generated internally by the LDOBAT.
4. No external load allowed.
5. If no current is caused by outputs (pad output current as well as current across internal pull-up resistors)
