●Output voltage depend on VSET bit
The 2bit data are stored into the VSET memory and output voltage change among VOUT1 to VOUT4.
VSET data are written into non-volatile memory array. Initial VSET data is 1, 0 in VSET[1:0] and VOUT is 2.9V.

●Input power supply regulation timing
①Using EEPROM PART
In case of using EEPROM part, be sure to raise Vcc1 up to operating voltage. In this time, Vcc2 has no connection with
operating.

②Using LDO regulator part
In case of using LDO regulator part, be sure to raise Vcc1 and Vcc2 up to operating voltage.
After rising Vcc1, wait 15msec and rising LDOEN.
When LDOEN is raised, Vcc1 must be operating voltage.
