millivolts of hysteresis to prevent spurious output activity
during power−up or power−down.
RESET Function
controlled by a low voltage detection circuit sensing the
V
RESET output stays below 1.0 V (0.1 V Typ) when V
is as low as 1.0 V to ensure reliable operation of
microprocessor− based systems.

tracking regulator of the standby output. By using the
standby output as a voltage reference, giving the user an
external programming lead (Adj lead), output voltages from
5.0 V to 20 V are easily realized. The programming is done
with a simple resistor divider (Figure 2), and following the
