The voltage at which the
STBY
signal is output when
Vout falls. The
STBY
detection voltage can be adjusted
by connecting a resistor between the STBYadj pin and
ground (R3). However, the
STBY
recovery voltage
cannot be adjusted.

The voltage at which the
NMI
signal is output when
Vout falls. (When NMIsns is connected to Vout.)
The
NMI
detection voltage can be adjusted by
connecting resistors between the NMIadj pin and Vout
(R1), and between the NMIadj pin and ground (R2).
