*1 This is the allowable loss of when it is mounted on a ROHM specification board 50mm×58mm.
When a substrate is implemented, the allowable loss varies from the size and material of the substrate.
To use at temperature higher than 25C, derate 9.6mV per 1C.

*2 Whenever the VBAT or PBAT or VIN34 voltage is under the LDO or SWREG output voltage,
the LDO and SWREG output is not guaranteed to meet its published specifications.
*3 VIN34 Power Supply can be externally connected to the VBAT and PBAT Power Supply when necessary.
*4 The DVDD Voltage must be under the Battery Voltage VBAT, PBAT at any times.
* This product is not especially designed to be protected from radioactivity.
