4 Pin Configuration and Functions

TPS798-Q1 DGN Package,8-Pin HVSSOP With PowerPAD (Top View)
The exposed thermal pad is connected to ground through pin 4 (GND).

PIN TYPE DESCRIPTION
NAME NO.
EN 5 I Enable pin. Driving the EN pin high turns on the regulator over full operating range. Driving this pin low puts the regulator into shutdown mode over full operating range.
GND 4 O Ground. The exposed thermal pad is connected to ground through this pin.
IN 8 I Input pin. Place a 0.1μF ceramic or greater capacitor from this pin to ground to provide stability. Both input and output capacitor grounds must be tied back to the device ground with no significant impedance between them.
NC 3, 6, 7 — No internal connection
OUT 1 O Regulated output voltage pin. A small (1μF) capacitor is needed from this pin to ground to provide stability.
SENSE/FB 2 I This pin is the input to the control loop error amplifier. Use this pin to set the output voltage of the device.
