Pin Function, Note 2-2

No connection. Leave NC pin floating.

No connection. Leave NC pin floating.

LDO_O pin connect to gate pin of MOSFET if using the internal

1.2V LDO controller.

LDO_O pin will be floating if using an external 1.2V LDO.

Note: When Pin126 voltage is greater than the internal 1.2V LDO

controller enable threshold (1V), the internal 1.2V LDO controller is

enabled and creates a 1.2V output when using an external MOS-

FET.

When Pin126 is pull-down, the internal 1.2V LDO controller is dis-

abled and Pin 125 tri-stated.

IN_PWR_-

SEL

I

A resistor divider: Enable internal 1.2V LDO controller.

Pull-down: Disable internal 1.2V LDO controller by a pull-down

resistor when using an external 1.2V LDO for 1.2V power supply.

— Note: A 4 kΩ pull-up and a 2 kΩ pull-down resistors divider network

is recommended if using the internal 1.2V LDO controller and an

external MOSFET for 1.2V power.

A 100Ω (approximately) resistor between the source and drain pins

on the MOSFET is highly recommended as well.
