Voltage regulator circuit
The boosting voltage occurring at the V

voltage) is output.
Because the S1D15A06 series has the high-accuracy
constant voltage source, the 32-level electronic volume
function and the internal resistor for the V
regulator (= V
high-accuracy voltage regulator circuit without external
component. And V
