Electrical Characteristics(6)

(MIC5373) VIN = VOUT + 1V (VOUT is highest of the three regulator outputs); VBIAS = VEN1 = VEN2 = VEN3 = 5.5V (ON);

(MIC5383) VIN = VOUT + 1V (VOUT is highest of the three regulator outputs); VBIAS = 5.5V; V/EN1 = V/EN2 = V/EN3 = GND (ON);

IOUT1 = IOUT2 = IOUT3 = 100µA; COUT1 = COUT2 = COUT3 = 1µF; TA = 25°C, Bold values indicate –40°C ≤ TJ ≤ +125°C, unless

noted.
