DESCRIPTION
Input supply voltage pin. Bypass with a 220μF capacitor to GND.
Not internally connected. For better heat flow, connect to GND (exposed pad).
VTT regulator output pin, which is preset to 50% of V
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
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.
VDDQ regulator output voltage pin.
The backside exposed pad which serves as the package heatsink. Must be
connected to GND.
