Pin Function

1

SW

Switch (Output): Internal power MOSFET output switches. Disable pull down 180

Ω

(MIC23164 only).

2

EN

Enable (Input): Logic high enables operation of the regulator. Logic low will shut down the

device. Do not leave floating.

3

FB

Feedback: Connect a resistor divider from the output to ground to set the output voltage.

4

NC

Not Internally Connected.

5

PG

Power Good: Open drain output for the power good indicator. Use a pull-up resistor from this pin

to a voltage source to detect a power good condition.

6

SS

Soft Start: Place a capacitor from this pin to ground to program the soft start time. Do not leave
