5 / 15 page ST5R00 SERIES 5/15 Table 6: Electrical Characteristics For ST5R30 (VIN = 1.8V, IOUT = 10mA, TA = 25°C, unless otherwise specified. For external components value, unless otherwise notes, refer to the typical operating circuit.) (1): The minimum input voltage for the IC start-up is strictly a function of the VF catch diode. Table 7: Electrical Characteristics For ST5R33 (VIN = 2V, IOUT = 10mA, TA = 25°C, unless otherwise specified. For external components value, unless otherwise notes, refer to the typical operating circuit.) (1): The minimum input voltage for the IC start-up is strictly a function of the VF catch diode. Table 8: Electrical Characteristics For ST5R50 (VIN = 3V, IOUT = 10mA, TA = 25°C, unless otherwise specified. For external components value, unless otherwise notes, refer to the typical operating circuit.) (1): The minimum input voltage for the IC start-up is strictly a function of the VF catch diode.
