PIN DESCRIPTIONS TPS717xx 1.5 ×1.5 SC70 NAME 2 ×2 SON SON (DCK) (DRV) (DSE) DESCRIPTION IN 1 6 6 Input to the device. GND 2 3 2 Ground. Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts the EN 3 4 4 regulator into standby mode, thereby reducing operating current. Fixed voltage versions only. An external capacitor connected to this terminal bypasses NR 4 2 3 noise generated by the internal bandgap, lowering output noise. Adjustable voltage version only. The voltage at this pin is fed to the error amplifier. A FB 4 2 3 resistor divider from OUT to FB sets the output voltage when in regulation. This is the regulated output voltage. A small capacitor is needed from this pin to ground OUT 5 1 1 to assure stability; a 1.0 µF ceramic capacitor is adequate. NC – 5 5 Not connected. This pin can be tied to ground to improve thermal dissipation. 5 Submit Documentation Feedback |
