Name Function
1V
S
Supply voltage, block directly to GND on the IC with a capacitor.
2R
es
Reset output. Internally connected to V
o
through a 20 KΩ pull up
resistor. This pin is pulled low when V
o
< V
o_th
. Keep open if not
needed.
3 GND Ground is internally electrically connected to TAB.
4V
cr
Reset delay. Connect an external capacitor between V
cr
pin and
ground to adjust the reset delay time. Keep open if not needed.
5V
o
5 V regulated output. Block to GND with a ceramic capacitor
(>
220 nF for regulator stability).
