Suggested regulator manufacturers:
• Torex (XC6215 series)
• Seiko (S817 series)
• BCDSemi (AP2121 series)
NOTES:
1) The central pad on the underside of the chip
is a Vss pin and should be connected to ground.
Do not put any other tracks underneath
the body of the chip.
2) It is important to place all Cs, Rs, Rx and Ry
components physically near to the chip.
3) Leave YnA, YnB unconnected if not used.
