Pin Function
Bias Supply. The bias supply is the power supply for the internal circuitry of the
regulator.
Ground. Ground pins and exposed pad must be connected externally.
Input Supply. Drain of NMOS pass transistor which is the power input voltage for
regulator. The NMOS pass transistor steps down this input voltage to create the
output voltage.
Output. Output Voltage of Regulator.
Power Good Output. Open-drain output. Output is driven low when the output voltage
is less than the power good threshold of its programmed nominal output voltage.
When the output goes above the power good threshold, the open-drain output goes
high-impedance, allowing it to be pulled up to a fixed voltage.
Adjust Input. Connect external resistor divider to program the output voltage.
Enable: TTL/CMOS compatible input. Logic high = enable, logic low = shutdown. Do
not leave floating.
Exposed thermal pad. Connect to the ground plane to maximize thermal performance.
