Noise bypass pin. For low noise applications, a 0.01-mF or larger ceramic capacitor should be connected from this pin
to ground.
Capacitor connected from this pin to ground will allow a delayed power-on-reset signal at the ERROR (Pin 7) output.
Refer to Figure 4.

Input supply pin. Bypass this pin with a 2.2-mF ceramic or tantalum capacitor to ground.
Output voltage. Connect C
For fixed output voltage versions, this pin should be connected to V
this voltage feedback pin sets the output voltage via an external resistor divider.
This open drain output is an error flag output which goes low when V
also provides a power-on-reset signal if a capacitor is connected to the DELAY pin.
By applying less than 0.4 V to this pin, the device will be turned off. Connect this pin to V
