FMA1125DC 16SOP Typical Application Circuit: Internal LDO
Notes:
• The voltage range of VDDH can be from 2.5V to 5V.
• 2k¾ pull-up resistors are required for I
• PA1 ~ PA6 can be configured as either touch input channels or DIO ports.
• I
• For LED dimming control through DIO ports, sink current circuit is mandatory as shown above.
• When PA ports are configured as DIO and used for LED dimming control, the circuit should be the same as DIO ports explained above.
• For External LDO connection, please refer to Case 1 and Case 2 in 24QFN’s External LDO connections.
