PIN DESCRIPTIONS
TPS727xx
NAME YFF DSE DESCRIPTION
Regulated output voltage pin. A small 1mF ceramic capacitor is needed from this pin to ground to assure stability. See Input
OUT B2 1
and Output Capacitor Requirements in the Application Information section for more details.
NC — 2 No connection. This pin can be tied to to ground to improve thermal dissipation.
GND B1 3 Ground pin.
Enable pin. Driving EN over 0.9V turns on the regulator. Driving EN below 0.4V puts the regulator into shutdown mode, thus
EN A1 4
reducing the operating current to 120nA, nominal.
NC — 5 No connection. This pin can be tied to to ground to improve thermal dissipation.
Input pin. A small capacitor is needed from this pin to ground to assure stability. See Input and Output Capacitor
