3.0 PIN DESCRIPTIONS
Descriptions of the pins are listed in Table 3-1.
TABLE 3-1: PIN FUNCTION TABLE.
3.1 Input Voltage (V
IN
)
V
IN
functions as the positive power supply input (or
operating input). An optional 0.1 µF ceramic capacitor
can be placed at this pin if the input voltage is too noisy;
it needs to be within 5 mm of this pin. The input voltage
needs to be at least 0.2V higher than the output voltage
for normal operation.
3.2 Output Voltage (V
OUT
)
V
OUT
is an accurate reference voltage output. It can
source and sink small currents, and has a low output
impedance. A load capacitor between 1 µF and 10 µF
needs to be located within 5 mm of this pin.
3.3 Ground (V
SS
)
Normally connected directly to ground. It can be placed
at another voltage as long as all of the voltages shift
with it, and proper bypassing is observed.
