SUPPLY CURRENT
†
V3P3D SWITCH
2.5V VOLTAGE REGULATOR
Unless otherwise specified, load = 5mA
LOW POWER VOLTAGE REGULATOR
Unless otherwise specified, V3P3SYS=V3P3A=0, PB=GND (BROWNOUT)
v1.0
Current into V3P3A and V3P3SYS pins is not zero if voltage is applied at these pins in brownout, LCD or sleep modes.
PARAMETER
