ST7565S
The Voltage Regulator Circuit
The step-up voltage generated at
driver voltage
Because the ST7565S chips have an internal high-accuracy
fixed voltage power supply with a 64-level electronic volume
(A) When the V5 Voltage Regulator Internal Resistors Are Used
Through the use of the V
and the electronic volume function the liquid crystal power
supply voltage V
(without adding any external resistors), making it possible to
