4 / 15 page ST5R00 SERIES 4/15 Figure 5: Typical Demoboard Note: drawing not in scale. Table 4: Electrical Characteristics For ST5R25 (VIN = 1.5V, 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.
