The AC adaptor for the KX-TCD725 provides unregulated DC through J2 for the handset charge
terminal, the 3.8V regulator (IC7) and the Relay coil (RL1) where fitted.
The 3.8V supply from IC7 is used for the RF module, and is further reduced by IC1 to 2.80V for the
BBIC supply.
R17, 18 and 19 provide short circuit/over current protection at the handset charge terminal.
