Pin Description

Supply Input

Regulator Output B

Voltage Reference Bypass: Connect external 470pF capacitor to GND to

reduce output noise in regulator “A” or “B.” May be left open.

Enable/Shutdown B (Input): CMOS compatible input. Logic high = enable,

logic low or open = shutdown. Do not leave floating.

Enable/Shutdown A (Input): CMOS compatible input. Logic high = enable,

logic low or open = shutdown. Do not leave floating.

Regulator Output A

Ground

Power supply reset monitor output. N-CH open drain output, must connect

through a resistor to supply voltage.
