Voltage Supply Input. Connect a 1µF capacitor between this pin
and GND.
Enable Input to Regulator 1. Active high input.
High = On. Low = OFF.
Enable Input to Regulator 2. Active high input.
High = On. Low = OFF.
Internal Voltage Reference Bypass. Connect a 10nF capacitor
from this pin to GND to reduce output noise and improve line
transient and PSRR.
This pin may be left open.
Set Delay Input. Connect a capacitor between this pin and GND
to set the POR delay time. If left open, there will be no delay.
Common Ground pin. Connect externally to exposed pad.
No Connection. Do not connect to any other pin.
Power-On Reset Output. Open drain output. Active low indicates
under-voltage output on Regulator 2. A pull-up resistor is required
for correct operation.
Output of Regulator 2. 300mA maximum current output. Connect
a 1µF capacitor between this pin and GND.
Output of Regulator 1. 150mA maximum current output. Connect
a 1µF capacitor between this pin and GND.
Common Ground. Connect to Pin 6.
