Notes: 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-
age VDD18.
2. The LDOBAT is a built in low dropout voltage regulator, which provides the supply voltage VBAT18 for the RTC, backup
SRAM, P9, P13, P22, P31, NSLEEP and NSHDN. The LDOBAT voltage regulator switches in battery mode if LDOBAT_IN
falls below 1.5V.
3. Supply voltage VBAT18 for backup domain is generated internally by the LDOBAT.
4. If no current is caused by outputs (pad output current as well as current across internal pull-up resistors)
