ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the specified operating
junction temperature range, otherwise specifications are at TA = 25°C (Note 2). VIN = PVIN1 = PVIN2 = PVIN3 = PVIN4 = VIN_LDO2 = VIN_LDO34
= DVDD = 3.8V. All regulators disabled unless otherwise noted.
