LTC3589_12 Datasheet, PDF (7/50 Pages) Linear Technology – 8-Output Regulator with Sequencing and I2C

LTC3589/LTC3589-1/
LTC3589-2
ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the specified operating
junction temperature range, otherwise specifications are at T_A = 25°C (Note 2). V_IN = PV_IN1 = PV_IN2 = PV_IN3 = PV_IN4 = V_{IN_LDO2} = V_{IN_LDO34}
= DV_DD = 3.8V. All regulators disabled unless otherwise noted.
