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.
