PIN DESCRIPTION
Pin Number
Name
Function
1
C
NOISE
Noise bypass pin. For low noise applications, a 0.01- F or larger ceramic capacitor should be connected from this pin
to ground.
2
DELAY
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.

GND
Ground pin. Local ground for C
NOISE
and C
OUT
.
4
V
IN
Input supply pin. Bypass this pin with a 2.2- F ceramic or tantalum capacitor to ground.
5
V
OUT
Output voltage. Connect C
OUT
between this pin and ground.
6
SENSE or ADJ
For fixed output voltage versions, this pin should be connected to V
(Pin 5). For adjustable output voltage version,
this voltage feedback pin sets the output voltage via an external resistor divider.
7
ERROR
This open drain output is an error flag output which goes low when V
drops 5% below its nominal voltage. This pin
also provides a power-on-reset signal if a capacitor is connected to the DELAY pin.
8
SD
By applying less than 0.4 V to this pin, the device will be turned off. Connect this pin to V
IN
if unused.
