The power supply of 1.5V is enabled by using recommendation FET shown in Figure 5-1. <Figure 5-1> 1.5V reference level circuit peripheral block • As for power supply ON, the order of DVDD33 power supply voltage (3.3V) to FET source supply voltage (3.3V) is recommended. DVDD33 DVSS_2 DVREF DVDD_2 DVDD_1 LC75056PE 10nF C2 10 F C1 3.3V 1.5V FET D S G * FET Recommended Device No. NTR2101P (ON Semiconductor) * C1 is the capacitor to prevent oscillation. In the range of operating temperature, make sure to maintain low ESR and the capacitance recommended value is 10 F because oscillation may occur when the capacitance value changes due to the change of temperature. Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product performance may not be indicated by the Electrical Characteristics if operated under different conditions. |
