Function
LDO2 input;
Connect this pin straight to the Buck converter output or add a dropper
in between to reduce power dissipation on the chip.
Voltage regulator 2 output;
3.3 V or 2.6 V, depending on the state of SEL_LDO2.
Block to GND with capacitor for stable regulator operation; selection of
capacitor
Tracking regulator 1 output;
Block to GND with capacitor for stable regulator operation; selection of
capacitor
Tracking regulator 2 output;
Block to GND with capacitor for stable regulator operation; selection of
capacitor
Enable input microcontroller;
High level enables / low level disables the IC except the stand-by
regulators;
