7. 5V Regulator (REGE, REGB, REGC, REGR, REGL)
Rev.1.0, Sep.16.2003, page 17 of 40
The 5V regulator with the external PNP Tr. included the internal gain resistors. It has the output current limit
function which needs the external current sensing resistor .
The explanation of the 5V Regulator function is as follows (Fig.7).
