PIN DESCRIPTION
Pin Number
Name
Function
1
CNOISE
Noise bypass pin. For low noise applications, a 0.01-mF 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.
3
GND
Ground pin. Local ground for CNOISE and COUT.
4
VIN
Input supply pin. Bypass this pin with a 2.2-mF ceramic or tantalum capacitor to ground.
5
VOUT
Output voltage. Connect COUT between this pin and ground.
6
SENSE or ADJ
For fixed output voltage versions, this pin should be connected to VOUT (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 VOUT 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 VIN if unused.
