PIN DESCRIPTIONS

Descriptions of the pins are listed in Table 3-1.

TABLE 3-1:

PIN FUNCTION TABLE.

3.1

Input Voltage (VIN)

VIN 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 (VOUT)

VOUT 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 (VSS)

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.
