I/O DESCRIPTION
NAME NO.
Regulator output. A capacitor greater than or equal to 10 µF must be tied from this pin to
ground to assure stability. A 47-µF ceramic output capacitor is highly recommended to be
OUT 1, 20 O
connected from OUT to GND (as close to the device as possible) to maximize ac
performance.
Control-loop error amplifier input (TPS7A4701 only).
This is the SENSE pin if the device output voltage is programmed using ANY-OUT (no
external feedback resistors). This pin must be connected to OUT. Connect this pin to the
SENSE/FB 3 I
point of load to maximize accuracy.
This is the FB pin if the device output voltage is set using external resistors. See the
Adjustable Operation section for more details.
Control-loop error amplifier input (TPS7A4700 only).
SENSE 3 I
This is the SENSE pin of the device and must be connected to OUT. Connect this pin to the
point of load to maximize accuracy.
Connect the thermal pad to a large-area ground plane. The thermal pad is internally
Thermal Pad —
connected to GND.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability..
(2) All voltages are with respect to network ground terminal.
