Not internally connected. For better heat flow, connect to GND (exposed pad).
Ground pin (analog).
Ground pin (power).
This pin is for V
enabled. During Manual/Thermal shutdown, it is tightened to GND. The V
output voltage is set using an external resistor divider connected to ADJSD:
where R1 is the upper resistor and R2 is the ground-side resistor.
In addition, the ADJSD pin functions as a Shutdown pin. When ADJSD voltage is
higher than 2.7V (SHDN_H), the circuit is in Shutdown mode. When ADJSD
voltage is below 1.5V (SHDN_L), both VDDQ and VTT are enabled. A low-leakage
Schottky diode in series with ADJSD pin is recommended to avoid interference with
the voltage adjustment setting.
