Protection
Positive side of the reference voltage, which allows remote sensing to obtain excellent load
regulation.
Negative side of the reference voltage, which allows to use resistor divider to set an expect
output voltage. A small bypass capacitor can be connected from this pin to ground to improve
PSRR performance.
For fixed voltage devices this is the bottom of the resistor divider that sets the output voltage.
Output pin of the regulator, which connects to the TAB. A minimum of 10 F capacitor must be
connected from this pin to ground to ensure the stability.
Supply pin of the control circuitry, which must be always higher than VOUT for the device to
regulate. (See electrical characteristics)
Power input pin of the regulator, which must be always higher than VOUT for the device to
regulate. (See electrical characteristics)
